    I have at least two instances of illegitimacy in my tree. In one of those cases it did cause the problem of cousins not being related. For that one, I was able to prove this to myself and identify my ancestor. Much thanks to the Quakers for keeping such great records! I don't know that I have it documented quite well enough so that someone else would follow the reasoning... I need to work on that.
    In another case, I can't prove it even to myself, but I strongly suspect illegitimacy and I have spent/wasted uncountable hours on it.
    I am pretty sure I know two families that are my ancestors, but not the two individuals. I am working on a 2nd cousin to upload her DNA to GEDmatch.

      I empathize !
      Gram raised me until I was 6, & I thought I knew her. I only recently understood that Mum (S) had been her grandmother- I have reason to believe that she'd only learned it when over 60 - and that opens every Pandora's box out there.
      I share matches with a 2C1R that point to the probability of her father having been 1 of 8 sons...none of whose descendants (so far) is an outstanding candidate. (My matches are loaded with their distant relatives, & descendants of Their siblings- so I think I'm on the right track. (Few records- not even a census til 1871) Generation-wise, this is my closest mystery- & the most meaningful.
      Just to keep things interesting, it seems that her grandfather- husband of"S" - bore no relation to the name (s) he used for life. (I've another swarm of matches- none of the same names as other gang...nothing to go on but DNA & trees.)
      Some of my other family lines are even less promising.
      You have courage- I wish you good luck!

      @@barbarabird3827 Thanks for sharing your story Barbara. That is especially tough for you to have these questions and uncertainties at you parent and grandparent levels. You had personal connections and now are finding out that their relationships are not what you thought. In my case, one of my illegitimate ancestors was my great grandfather. And there was so much more mystery to that man because he had the family with my grandmother in PA and a second/overlapping family in Indiana. I very amazingly have a letter between my grandmother and her sister where they discuss it. That is a long complex story I won't bore you with but it is unsettling to know how tough my grandmother's life was. And two of her sisters (1 for sure and 1 I suspect) had their own illegitimate children. The other illegitimate direct ancestor I mentioned in my original post is quite a few generations back on a different branch. I feel a bit more detached about that one.

    I had my Genealogy done and it came back I'm related to royalty, presidents, and many historical famous ppl.
    It breaks it down how we're related. I find DNA fascinating and how it works!
    How its broken down and intertwined together to prove blood relations!

    WOW! So wait we do have Endogamy through the same family lines further back on the tree like in the 1600's-1700's so we knew our parents were distant cousins. I have A LOT of relatives that share DNA with both my mother and my father. For sure our 1% is high as I see a match to both on every other page on ancestry. It is making it very difficult to figure out our surname match origins on my father's side we know who they were and where they were from on one side but the other side we are also getting the same location matches from my mother's side which should not be happening as the families were in different locations over time. We literally have a well published paper trail from the family's first entry into the New Spain and all the way back to the Houses of Europe. Same with my mother's for the most part however the other side of my father's family we can only date them to the early 1700's in the New Spain/ California. My father's side who could not be tested is showing markers in the same Spanish Fort in the U.S. like my mother's. This would not match the paper trial we have and are at a loss.

      One strategy to cut through endogamy is Y DNA. As long as any line has not "daughtered out" you can test, and it will cut like a laser back to before surnames, especially if you join a project with good, knowledgeable admins.

    Think I have a half 2nd cousin twice removed that shares 2% of my DNA. It was easy to rule him out as a 2nd cousin since he was pure European. I thought it was interesting he had no African in him since I'm black. All my great grandparents were black but never met any of my 2nd great grandparents. Was thinking maybe he was my grandmother half 1st cousin since he shared so much DNA with me. My dad only shared like 8 more CM with him so I guess I just inherited an unusual amount from that part of his DNA. Now I think he's probably my grandmother half 2nd cousin. Even think I found the great grandfather they share. Yeah it can be interesting seeing how your relative to certain matches.

      I have the same issue, but I can’t figure out how we’re related. I’m pretty sure my cousin (who shows up as a match on 23andMe AND Ancestry) is a 2nd cousin once removed, given our respective ages and the shared cM, but she’s black with a small amount of European ancestry and I’m white with a small amount of African ancestry, so I can’t even tell what the background of our shared ancestor might be! Added to that, we both have extensive family trees built out but there is zero overlap, except for the fact that they all lived in the same area at the same time.

    I have a real serious question because me and my mother show on DNA ancestry that we are 1st-2nd cousin to this same person my mother and her share 887 cm and 22 segments . And me her share 458 cm and 16 segments. Is it possible that she is my mother niece . Please I would like a answer why would it have us Both as 1st-2nd cousin.

    Is a half sibling the same as a step brother or sister? I am having a hard time figuring out how you could have a half cousin? I would think you would either match them or not match them. I guess this doesn't really apply to my search I have no information on 99.9% of the matches.

      Half cousin: you share 1 grandparent rather than 2..
      Step brother etc: no blood relationship.

    • @KentPetersonmoney
      @KentPetersonmoney Рік тому

      No you still share blood with a half sibling. With a step sibling you don't.
