I have a couple of illegitimate ancestors a few generations back just like you.

I care!

Hello Everyone,
I have found this discussion very interesting. I have a male cousin who just might be my biological brother. I am getting is Y-DNA now to see if and exactly how similiar ours might be. There are some major family secrets around all this so I want to be accurate and I want to be discrete. My assumption is that if my cousin and I are brothers to a common father, we would match with the Y-DNA test. Is that accurate?
Thanx,
Bob

Hi Bob,

Your question is a loaded gun, indeed! You are correct that your biological brother (who is officially your cousin) and yourself would indeed share the Y-DNA as your biological father.

What complicates matters is that if this alleged sibling is on your biological father's side of the family, his Y-DNA, your Y-DNA and your biological father's Y-DNA would all be the same anyway even if he is not your brother, i.e., paternal cousins share the same Y-DNA.

same males from same male ydna lines match but will their mtdna?

i have a lawrence denning born to theresa denning no father listed theresa disappears but her sister mary denning has lawrence adopted as larwrence dunlea. the only unknown is whose the dad?
lets assume it isnt the james dunlea marys hubby. but maybe since its from chelsea ma. just maybe the ydna is common there.
you test their decendents and you establish lawrence mtdna it would match both real mom and adopted andhis siblings of mary
so then you test his ydna and his step brother james jr. lets say you dont know the genealogy or anything about theresa. james and larry match mtdna but what about ydna if they didnt match . the decendents would assume mary cheated. what if they dna matched then you would suspect notihing happened but since we know would that deffinatly mean james did both?
no

and thats just 17 people

good luck making that jump. sometimes you need to understand this stuff happens maybe theresa died in child birth and the child just went to her sister.

one thing that happens in this case is you would be forced to look for why and that would lead you to this answer .its in the paperwork. it wouldnt be a denning we are e3b1 s
