    I have exactly this problem. I'm trying to prove who my father is. My 3rd cousin has documented my paternal side really well and I have many Paternal DNA cousins. My potential father is deceased and an only child and my potential half brother is unwilling to do a DNA test. To get over these stumbling blocks, I am trying to prove who my paternal grandmother is via DNA matches. The problem is on my maternal side my grand fathers line is not as the paper trail says so there are loads of distant cousins. It is hard to figure out how we all fit together. Its a whole can of worms to untangle but I like a good puzzle.

      Yep. When you have the kind of roadblocks you've mentioned, it can be difficult. See if you can figure out who the half-brother's half-siblings or full cousins might be. There are ways to filter your DNA by using these folks who you know how they are related to someone on your family tree.

    I had my mother tested 3 years ago, she was 96 at the time (she died at age 98), plus her 1st cousin on her father's side had also tested. I was able to use that to separate her mother and father's side. That was all very helpful. My father was an only child, he died over 50 years ago and both his parents are of course deceased. However, the son of my dad's first cousin on his mother's side has also tested, that was also helpful.

    I wish there was an option to go one step beyond phasing, in that a DNA profile would be created and used as an individual for matching. So if I use my father's, brother's, sister's DNA file and perhaps a maternal uncle, I could create a file for my deceased mother. My DNA, my brother, sister and uncle create the overlapped segments and my father's DNA is used to minus out his segments.

      The more children and cousins you can have tested the better. As you know, Devon's parents were deceased before we could test them. Her father was an only child. However, on his side, she tested his living 1st cousins. We also tested her two aunts, her mother's 1st cousin and Devon's 1st cousin. We also tested Devon's brother. We have not fully replicated her parent's DNA but she has captured more than nothing. Do the best with what you can to test all the 'surrounding' relatives of your parents.

    My mom told me a guy was my dad for 18 years , one day his wife came to my door and provided me with a DNA test saying that he wasn't the father . Then my mom told me that another guy was my father and I do look like him a bit , but the messed up part is she told me 2 months after that guy had died . So if he is my dad he never knew he had a child cause my mom said she didn't tell him . I'm just trying to find out how I can know for sure since he's gone. He didn't have any other kids so no siblings I can test with . I might be out of luck .

      You're not entirely out of luck. If possible, build a genealogical family tree for the second man. That way, you become familiar with the names of the persons that could appear in your tree if you match. You'll also need this to find potential persons you can test to substitute for that second man. Check out this video that explains why.

      First, take a look at the Shared cM project tool to see all the possible relationships you have with someone that shares 1320 cMs. dnapainter.com/tools/sharedcmv4
      Next, start seeing how other DNA matches that also match that DNA match match you. You could develop a WATO tree to analyze your findings and confirm where people should appear on the family tree based on the tree you've build, the shared cMS and probability statistics. ruclips.net/video/d6LxMH0zS54/видео.html

    @richarddcamp1773 3 года назад

    First, let me say I love your videos! Keep them coming - maybe one day I'll finally understand everything you are telling us! In my case, my mom died (quite young), and then her sister died (also young). Their brother, my uncle, is still living (97 years) and I did convince him to take a DNA test (Ancestry). They were just the three siblings. His daughter, my first cousin, also took a DNA test, but no one else from that family so far. My mom's sister has, so far, had one son (my cousin) take a DNA test, and then (so far) one of my brothers has also taken the Ancestry DNA test. Is it possible to come up with a similar chart using first cousins (my sibling, or two of mom's children) and one sibling (her brother) and his daughter and the son of their third sibling? I have samples of my mom's hair (from her baby book, etc.) and I have thought about looking into getting that DNA tested, but I guess no company does ancestral DNA testing from any other samples than saliva. :o( I am holding on to it in case that day comes. In the meantime, having my uncle's DNA has helped me isolate ancestors from my mom's side of the family from my dad's. (Dad also took a DNA test, and he is still living). I don't know why it feels important to me to find this out, I knew my mother and loved her - that should be enough. But, there have been some surprises on my maternal line, so it would be fascinating to know how that shakes out in me and my brothers. - Oh yeah, is there a difference in the DNA being mitochondrial or not in this type of breakdown? I noticed you used only the male line to determine the missing male parent. Does that make this equation different?

    • @FamilyHistoryFanatics
      @FamilyHistoryFanatics  2 года назад

      So many great questions. Focus on building your family tree using the genetic matches you share and that your cousins and so on (who have tested) share with you and your matches. You can use the autosomal tests you've likely taken (Ancestry). Learn how to make a Leeds Chart and also how to do triangulation. I have several videos on these topics, as do other genetic genealogists.
      I wouldn't worry about mitochondrial DNA or y-DNA at this point. There is so much you can do with autosomal that I wouldn't put any energy here.
      As for DNA from hair. I did make a video about this topic ruclips.net/video/zYkJckKpgrE/видео.html
      But again, I would focus on using the DNA matches you share in common with your relatives who have taken DNA tests first. When you've figured out how you and your known relatives match all of your Genetic matches who share more than 40 cMs with you, then you can explore the other test options.

      Testing any known relatives to help you sort through your DNA matches is helpful. The double first cousins will present a number of problems. So see if you can find cousins who aren't doubles. Halfs work wonders as well.

    My question pertains to painting the segments onto DNA painter. I presume the deceased parent is the base so who do you compare the test kits with to get the segments to compare? Or is the base you and you compare to your other siblings to yourself and to your deceased parent's sibling (s) to yourself? If you have a phased kit for your siblings and yourself, to whom do you compare that to in order to get segments to paint?

      If I'm reading this correctly. You have 2 children being tested along with their mother. That would definitely help filter the DNA match results for the children between their maternal and paternal lines. If you also test the father's nieces and nephews, that would create more triangulation points to father your research.

    • @FamilyHistoryFanatics
      @FamilyHistoryFanatics  2 года назад

      Your question is two parts. A child can only have DNA that their parents have if that location is a mutation. However, those mutations are few. Thus, you first need to ensure that the child is indeed a biological child of the parents based on the amount of shared cMs between them.
      Then, yes, the children can have ethnicity results that aren't in common with their parents because the algorithms are comparing your DNA to a reference population. Not all ethnic groups are represented (or represented in significant amounts).
      I recommend ignoring the ethnicity results and focus on building genetic trees using DNA matches. The ethnicity results are a 'party trick' but the real answer to your heritage comes from building your family tree.

If I choose to have those tests processed, can they then be exported to other platforms I have shared the Ancestry DNA Data with (eg. My History, Family Search, Geneanet, Geni, etc)? If they can, does it reveal or confirm additional relatives and insights?

    • @FamilyHistoryFanatics
      @FamilyHistoryFanatics  Год назад

      Multiple questions to answer:
      If you're the oldest of your line, taking a Y-DNA or mt-DNA test might not help you at present (or anytime soon), but you could leave your results for future research, particularly if you line your DNA to a documented family tree.
      Y-DNA and mt-DNA are primarily a FamilyTreeDNA and mito-yDNA platfom test. They aren't accepted by MyHeritage.
      You can export your Ancestry DNA results to MyHeritage, Living DNA (if you have UK ancestors), Family Tree DNA, and GEDmatch. I would recommend that you transfer your DNA and upload family trees to each platform. Then let other researchers utilize DNA matching to build off what you have made available. I explain the downloading process in this playlist ruclips.net/video/-Z4vyKuSXa4/видео.html
      Geni, FamilySearch, and I believe Geneanet do not accept DNA data. But they do accept family trees. We have videos about how to add your family tree to FamilySearch. They are a collaborative platform and the process can be slow depending on how many persons you're trying to amend or add to the tree.
