DNA tests

[jon attwood]

One of my Great Grandfathers was born out of wedlock, and his mother later married, there is some speculation as to whether the man she married was his father.
I know the parentage of his siblings and can trace that line down to living people.
So if I had a DNA test, and so did someone I am sure is descended from the possible Gt Gt Grandfather would it be possible to establish if we share an ancestor 4 generations ago?
I know this technique can be used to prove parentage, but would it work going back 4 generations and then down again?, and if so how reliable would the results be?

Any ideas could be very helpful, as I might have been researching people who are absolutely no relation for the last few years!

Hi Jon

How long was the timescale inbetween the birth and the mothers marriage?

Have you found your great grandfathers baptism?

Jon,
I am interested if you ever went ahead with this,& if it helped. I have a similar situation in my family.My Grandmother was born out of wedlock, & I feel that her 'Father 'not named on birth certificate, was no the man who my G Grandmother married.
I am thinking of having this DNA test done, but not sure what it would prove.
