I was adopted but with exhaustive work my ancestry was documented and I was admitted to the Daughters of the American Revolution (DAR) two years ago. What's exciting is that Familytreedna test results also validated my documented ancestors by showing shared DNA with other Whittlesey cousins. It was exciting to learn that the impartial test results also proved my ancestry is true and there is no mistake in the documentation. My Ancestrytest results found my biological father and a sister I didnt know I had! DNA Genealogy is an exciting new field.
I had similar experience!!
Congrats on your successful Ancestry discoveries despite the initial challenge of researching your ancestors when you're adopted. Many adoptees don't have that experience.
OH MY GOSH, Devon - I’m only half way through and I had to pause to tell you this: you are the FIRST person to explain this in a way I fully understood.
FINALLY the light came on. Thank you!!! Keep up the great work!
😀😊I'm so glad!!! I will keep trying to do my best so I can have comments like these.
I've been working, no struggling, with genealogy for the last nine years and still know so little abt its intricacies. Since finding your site, I feel my knowledge base has increased significantly. I've told several friends abt your site. Hopefully they'll subscribe. Many thanks.
You got this! Keep watching and always ask questions. We love them!
Thanks for sharing our videos out to your friends. That's how we grow.
That was a great way to slowly explain to people new to DNA matching and Ancestry Thru-lines. It is so important to be methodical rather that click and add without research verification. Keep up the good work!
Thanks so much BlueV. I taught this information to a class at my local library and I quickly understood the need to slowly explain ThruLines
I agree with BlueDV. You did a great job of explaining the problems with ThruLines and the importance of doing the genealogy research.
Thanks Patricia
I've never taken trees posted on Ancestry at face value. I've seen people include some of my relatives in their tree just because they had the same name. When I've tried to get them straightened out, it always ends up even more botched up.
That is definitely something to be aware of with member trees on Ancestry.
So helpful as always. You explain everything perfectly ❤️
Thanks so much Ruby. Glad to help you out.
Good video, Devon! Looking forward to the next one :-)
Awesome. Thanks so much. (BTW... I released the next one too soon, so hang tight for those.)
Thank you. Another excellent presentation.
Very welcome
Devn, thanks so much for this series on ThruLines and especially for pointing out the pitfalls to watch for.
My question concerns whether a concerted effort from genetic genealogy leaders might ever be successful in persuading Ancestry that they really do need to add a chromosome browser? Of course, like everybody else, most of my best matches are on Ancestry, but they are not interested in transferring their data to FTDNA, MyHeritage, or GEDmatch and are certainly not interested in paying for a 23andMe test.
Oh how I wish that were the case. Ancestry responds to the masses (their paying customers). I would love a customer driven request for the chromosome browser and think it would be more motivating than genetic genealogy leaders requesting it.
ThruLines is as good as other peoples' research. For example, a good half of those researching my Holland ancestry have simply copied erroneous work conducted by others ('Oh look - it's in print; her name WAS Mary, so it must be right!'), and have linked my ancestor with a family existing 200 miles away. The dates may be approximately correct, but to keep going back to Somerset from London for every baptism is stretching belief a little. My real ancestress was from the parish just next door. If only everyone would look at the maps and use a little logic! Having said that, I find that 95% of the results accord with the documentary evidence I've collected down 55 years of research.
Thanks for your input. Much appreciated.
Thanks for this, interesting, cheers.
Very clear explanation. One problem with taking the DNA info to another service is that the Ancestry matches may not be on the other services. I know we can try communicating with the matches, but often you don't get an answer. It's just frustrating.
Yes, the Ancestry matches might not be on the other platform. But, different matches might be there that Ancestry doesn't have. Thus, I advocate being in as many databases as you can afford and manage.
Folks not responding is evidence that not everyone who tests did so to find cousin matches. Most wanted a quick answer to where they come from - so ethnicity estimates. The good news is that there are many techniques that help us work around the lack of communication.
The problem with ThruLines is the Evaluate. Unless you go look at these folks tree person and all the information it will bring into your tree if you accept it even after scrupulously meticulously examination you will most likely end up with multiple duplicates. If you blindly accept the person and their tree was built using hints, they may have five duplicate children, children that don’t really exist etc. Thru lines is cute but dangerous. Also many folks do not follow genealogy standards of data, you will spend lot of time correcting dates, un capitalizing surnames, standardizing places, you may as will if there info is valid add the person manually in your tree and save yourself a lot of correcting.
Very well said. You have to evaluate the theories or you'll kick yourself later.
Thank you for this! I was trying to figure out how TrueLines and ThruLines works and how accurate they are.
You're very welcome!
There's another element at work here, too. By the time you get back, my example will be 7 generations, those matches could be to a different ancestor behind a brick wall, for either party in the match. For my example, I have 118 matches showing on my ThruLines through 15 of the 16 known children of A.A. Some of the matches on several lines, other than my own, are in the 15 - 19 cM range and that might be the correct ancestor for the DNA match or not. But I would venture a guess that at least some of the matches are representing a different ancestor, since nearly all my lines are in the southern migration routes and at that distance I have found quite a few people that I'm related to by more than one route at that distance. That many people still carrying an ancestor's DNA for 7 generations is a bit of a stretch, even for a prolific family like this one. As you said, until you get them triangulated through a chromosome browser, it's not confirmed.
Thanks so much for your insight. There are a lot of factors in play to be sure.
Someone working on the same family lines as I do entered two great grandparents incorrectly and it was copied by many others. Those wrong ggrandparents showed up in my ThruLines, much to my exasperation. I contacted several of those people, giving them the correct grandparents and the verifying documentation. It was over a year, but finally those incorrect entries are finally gone from the ThruLines. The info in those ThruLines depends on the correctness of individual trees. I wonder if possibly the improved DNA relationships might now have a hand in the ThruLines?
It COULD be possible that ThruLines and the parental divisions might intersect. But folks have to remember the ThruLines are only as good as the trees people build.
Very gd and well explained
Glad you liked it
Can you do a video about thrulines in endogenous populations?
I'll put it in the suggestion list for sure.
What you described is exactly what I have found. Example: I’m related to a John Barnes b 1796 who was in IN at an early time. However, there is another John Barnes also in IN at the same time that other researchers have connected to to same parents as my JB. (I think mine is correct) nevertheless through lines showed me connected to the wife of the other JB.
Thanks for sharing a specific example. I wish Ancestry would allow us to reject ThruLines with explanations, but that's not currently an option.
I'm searching for my Smith line. I had to start with little information. I've been able to narrow down to towns/counties, but there are SO MANY 5th and 6th cousins that don't appear to be related for centuries. How does one find the correct line with a name like "Smith"? Which 6th cousins are in the correct line?
Also, why do I get cousin matches from people who have no trees?
First, your DNA matches are based on genetics, not trees. You might be able to figure out how a cluster of folks are related because one person in the cluster shares a tree.
5th and 6th cousins... is that an Ancestry term or have you found that relationship to be accurate? If it's an Ancestry label of how you're related, I would actually recommend you using one tool to see what is the likely relationship. dnapainter.com/tools/sharedcmv4 Type in the amount of cMs you share with your DNA matches and look for the possible relationships. You will find that you're related further removed than you think.
I have an interesting issue and haven’t figure it out. About ten years ago I did my first dna test, y-37. The results floored me. My results say I’m a Wells descendant, Not a Jackson. However my paper trail is saying I am. Then lately I took a couple of autosomal tests, no Jackson’s or Wells showed up. Then I upgraded my y to y-111. I have again matched a Wells and no Jackson’s. I am so confused on my dna findings that, genetically speaking, I don’t know who I am. Through Lines did not help and I’m still trying to figure why my dna brought “muddied waters”. So am I a Jackson or am I a Wells or both? I am so confused!!!
The problem could be that there are so few people who have taken y-DNA tests. Additionally, your paternal line surnames could have changed for you or your matches somewhere up the family tree and someone isn't aware.
ThruLines can only suggest back to your 5th great-grandparents. If your y-DNA matches are connected further back than that, ThruLines won't help you.
I recommend determining how all of your close matches (first cousins - 4th cousins) are related before you tackle the y-DNA issues. That foundation will help you determine your paternal line more quickly, even if you are working on your maternal lines.
Fantastic! Understood it all except for the "matches descend from multiple lines" part at the end. Is there an easy way to explain that? How would I tell this I guess is my question.
If you see DNA matches that descend from multiple children and grandchildren of the common ancestor, that's likely a better ThruLine theory than if all your DNA matches have share one direct line from you to your common ancestor with no distant cousins. Does that help?
@@FamilyHistoryFanatics yes thank you! 😍 you guys
So does it mean that dna would show matched with others but it maybe false and we may not be related to them.
Yep. Or, you may be related through a different line.
How can ThruLines link to inner branches ancestors??///
I have watched hours of HFH videos and there is something that I just don't understand. Are people engaged in DNA research only interested in identifying their closest "cousins" and grabbing their email addresses? Thrulines is the only tool where I can figure out how to view the Trees and related Records from the people with whom I share common ancestors. I'm not really interested in cousin pen pals. Am I missing something?
Contacting cousins and obtaining their emails is a way to attempt to collaborate and share research. Many folks who discover common genetic relatives are trying to access home sources such as letters, diaries, photographs, and other such records not available in accessible genealogy sources.
While others are trying to discover their blood lines (adoptees and illegitimate children and such.)
There are many reasons why folks use genetic genealogy to assist in their research other than finding 'pen pals' as you said.
I look at the Thru Lines matches as "potential" and go from there.
I find the ones that have public trees and check to see if they have sources. For those that have sources I check those out and see is it something I have or is it something new which could be helpful.
I did my research starting with the more current and working my way back. That is a linear pattern most researchers follow.
I might know where my 4th great grandfather was in 1820. I may know where his sister was in 1820. However, she may have a descendant who knows where one of her descendants was in 1940 or 1880 and has that in their tree. The reason they know that is because they also worked their way back in the same linear fashion BUT on another branch.
That is one of the features of Thru Lines that can be potentially helpful to me.
Thanks for sharing your research process with ThruLines. You're definitely being methodical.
@@FamilyHistoryFanatics Then again I also honestly enjoy doing logic puzzles and don't use the little "score card" they have attached to them. I have created my own system and do them in spiral notebooks. I think I've started on like my 5th or 6th spiral notebook of those ;-)
I check the sources too. I find that some people's sources are very suspect also, just as bad as copying from someone else's tree.
@@jjbud3124 Yes it takes time and effort to figure out how to find those little nuggets. I think what has really paid off for me is to use Family Search microfilms and go searching through them myself sometimes scanning them one page at a time. Or even in Ancestry to not just use the Search results but click on those original documents as well like the original Alabama marriage indexes -- the ones that are in typescript with the coded numbers for the counties and the dates of marriage.
Or go to official state and county archives websites. Very surprising what can be found there. A number of North Carolina counties have the original microfilmed land records going back to the 1700s for example. The Library of Virginia website is gradually filming all of their counties' Chancery Court records. I found new information for the Chandler Family Association just by scanning through those.
Right now I'm primarily focusing on my Italian ancestry including taking an online Italian course to get better at it. I think I go through phases where one thing interests me more and I'll do that for awhile. I have seizures and sometimes I have memory problems and last week is a blank space in my head so I do what I can do. At least it keeps me from getting bored ;-)
I am very leery of what I call the "stick" tree on ThruLines, where all the matches to a proposed 3rd great grandfather, for example, are with DNA cousins from the same 2nd great grandfather. I have had a couple of those "sticks" prove to be correct, though, if I could get back to, for example, the 4th great grandparents and found numerous DNA cousins descended from the siblings of the proposed ‘3rd great-grandfather’. One of those caused a brick wall breakthrough that had stumped several family genealogy researches for decades. So, yeah, be very cautious, but don’t quit investigating just because there’s a weak correlation.
Oooh... I like that term "Stick Tree.'T that's exactly what I'm cautions of.
What do you do when a ThruLine is wrong? Can you get Ancestry to change it?
Great question. There is no way to change the ThruLine at this time. Ancestry is considering offering the option to reject a ThruLine but it's not available yet. So for now, ignore it.
The other option is to contact the folks with the incorrect information on their trees. If they change their trees, then the ThruLines change.
@@FamilyHistoryFanatics Thank you so much for your reply! I appreciate it so much!
Thruline misidentified the parents of one of my ancestors and then listed the wrong ancestors for her for several generations prior to her birth. The error is an obvious one. I know the birthdate of my ancestor from her New York State death certificate. Thrulines identified another woman also named Jane Edwards born ten years later also in New York State. This wrong Jane Edwards married an entirely different husband and had different children. And this wrong Jane Edwards died in Michigan.
I have a similar problem. Thru Lines is connecting me to an incorrect pair of ancestor and it is driving me crazy seeing them listed as potential ancestors! Not to go into too much boring detail, but my ancestor was born in Ireland, and not Virginia which Thru Lines is trying to tell me. I hope that they will offer the option soon to reject inaccurate links!
I have an ancestor which is my second great grandmother on my tree...the thrulines are very incorrect...this ancestor was once a slave and on thrulines possible parents were popping up who were both white. I knew it wasn’t possible and I researched that family confirming that wasn’t my particular ancestors parents. They had the same name in the same place but different races...how do I tell thrulines that they aren’t her parents? My other DNA matches who have her in their tree really didn’t pay attention to the differences.
Sadly, there isn't a way to reject the ThruLines. Keep adding specific information into your tree that differentiates your ancestor from others. Also, reach out to Ancestry and suggest that race be a factor in their algorithm. Finally, reach out to the people with the ThruLine recommendations to see where their trees and yours can be improved to increase the accuracy. Just remember, ThruLines are possibilities, not necessarily confirmation.
You can do whole genome sequencing and match you dna to remains from nearly 10000 years ago. Genetic archaeology goes well beyond the 120 that Ancestry dna has to offer.
That may be true but I am concerned with identifying each person from my parents to my multiple great grandparents and a full sequence doesn't really help me know those details.
@family history fanatic but the way the royal line is found doesn’t care if you’re only related to 120 they still trace the royal line through as many generations that they need to find the next royal heir. So please keep that in mind so basically the only being related to 120 people doesn’t actually matter at all if you’re trying to prove your claim to royalty.
The 120 ancestor count applies to genetic. Anyone trying to find an heir (royal or not) will involve numerous generations. Typically they will use documents to establish relationships rather than genetics. Even then, a genetic claim will be weak past the 5th generation so it won't stand alone.
@@FamilyHistoryFanatics true but as long as you can trace the lineage of the tree and you have documentation then that`s all the prove you need right? I ask because I am rel;ated to thge 6th Duke of Sutherland and King Long Shanks
The expert on Americans of Royal descent is Gary Boyd Roberts of NEHGS in Boston, Mass. He has published several books on the subject with frequently updated editions. I have no known Royal ancestors from any country. One note of caution: incidents of false paternity (cuckholding in the vernacular) are known from DNA studies of the Pantagenet lines of the British Royals. This became evident after the remains of Plantagenet King Richard III were found and DNA studies were done. It will probably never be known where and when these false paternity events occurred or how often such events occurred. Richard III had no known offspring which complicates the analysis. So even though you have a well documented paper trail descent from a Royal line, it may still be inacurate. False paternity events occur periodically in all lines Royal or not.
What I don't understand is my dna has northern european, no jewish, my great grandfather and his family are jewish! Why don't I have askanazi in my dna?
ThruLines won't reveal that information. With DNA, sometimes you don't inherit the genes that would connect you to the ancestry you hope to find. Have you seen this video? ruclips.net/video/rMBooDoB2Wk/видео.html
I’m not following you...the thru lines say there are shared dna between myself and these ancestors of old.
Yes. That's what the DNA Thrulines suggest. But, once the line begins comparing your online family tree to the online family tree of the DNA match, you're left genetic comparisons and are doing tree comparisons.
In many cases, you could be related to the recommended common ancestor on paper, but genetically you're related through a different couple genetically. This can happen due to what's called Tree Collapse. For instance, I have ancestors from the little escarpment between Lake Erie and Lake Ontario. These relatives intermarried with each other, but not to the extent of endogamy where people have intermarried so much over many generations that it's very difficult to separate the generations with DNA. In any case, while I could share a common ancestral couple with a DNA match through the Comforts, it's quite possible it really is the Lanes one generation back further but either I or my match doesn't have this generation in our tree or Ancestry doesn't put for that theory. This is one time where MyHeritage Theory of Family Relativity is better. They show you multiple possibilities. But it can only do that if records and family trees make those options available.
Do you even work, for ancestry?
I don't. Which allows me to share my positive and negative opinions from my experience as a user rather than a spokesperson from the company.
If I wasn’t confused I am now
Sorry that is the case. What part confuses you the most?
ThruLines ain’t so clever. Suggesting new maternal ancestors from a tree where my DNA link is paternal. That should be a basic coding fix in the ThruLines application.
ThruLines do have their problems. I just try to help people become aware of them.
