Hello everyone,
I have a question concerning DNA Triangulation and confirmation of DNA descandants.
I have a match with my fifth cousin from my fahters side. Both of us are in a direct paternal line to our commen ancestor [[Johannes Wilhelm Behler|
https://www.wikitree.com/wiki/Behler-91]]. The family tree to this point is pretty well documented and the match at myHeritage is even suggesting he is my thrid cousin since we share a rahter large DNA segment of 66 cM.
Reading the DNA Traingulation page and specifically the three legged stool segment I was looking for another descandant that might also share the DNA segment in order to get DNA confirmation until my 4th GreatGrandparent.
Wilhelm had 4 children. I am decenent of the younger brother of my matches thrid GreatGrandfather. The two sisters either died young or never married to my knowledge.
Going one step further my ancestors children also died young or never married except for my direct ancestor and the same goes for my matches ancestor.
Going a generation back only our commen ancestor is found in the chruch book so this doesn't work either,
I have a match to my second cousin, but she is his fifth cousin as well, since she is descandant from my part of the family tree.
Any idea how I could still confirm the DNA relation to our common ancestor?
Thanks in advance
Jörg
