Ancestral Family Tree DNA Testing / Some folks DNA related to me but not my cousin who also took a test
« on: Thursday 23 November 23 23:14 GMT (UK) »
Hello.
I had some really good luck getting my DNA done. First thing I found was a very close relative that turned out to be a first cousin. Turns out our mothers were sisters and the lifelong mystery of who was her father was solved. That opened up a big part of my mother's family tree which was nice.
On my father's side ... the man on his mother's birth certificate had actually been dead 10 years before her birth. Her real father was another complete mystery. Nothing really popped out on the DNA match screen the way it had on my mother's side.
My 2nd cousin ... the son of my my father's sister's daughter ... took the same type ancestry DNA test. I see him top of the list as a match. I use him to compare to potential matches that I have.
Here's my question. I noticed at a certain point if you go back he will not show up as co-related to people who are related on my father's side. I believe it takes going back 7 generations and then this cousin does not show up in my thru-lines.
I found what a bunch of clues that seem to point to an individual on the DNA match screen being a relative of the man who fathered my grandmother. But ... my cousin does not show as DNA-related to this person. I count the generations between this person and the potential parent and it's 4 (after him the potential parent is the 4th).
I'm wondering if the 4 generations plus the fact that i'm comparing to my father's sister's grandchild would have a water-down effect? Making it so he might not show up as co-related.
Sorry for explaining it so bad.
Any help greatly appreciated!
Thanks.
