A man was born illegitimatley in 1867. How much of a chance would his g.granddaughter have of being able to find any common ancestor.

Do you have his mother's details? If so, you have as reasonable chance of finding other descendants of her line as of any of your other lines (although saying that, my grandfather was one of 14 children and I still haven't found anyone else researching the same line!). I'm not totally clear on the DNA side of things, but I think if you are trying to make a potential match via the male side you would need to be male yourself and to be descended from a son of a son of a son of this man to make a match to any direct male descendants from him or his father/grandfather.

Hi Ermy.
Yes I know you trace from father to son. etc. But this is a g.granddaughter and wondered if it was possible to get a match.I know she would have some of his DNA but just how much, is the question.

Hi Mary
If you google DNA testing it will give you all sorts of information

Hi.
Yes I`ve done alot of googling, and read about the Y DNA and mtDNA but still not clear if it`s at all possible to be able to trace from the g.granddaughter to the illigitimate g.grandfather,or his father before him.
This man(John) had a half brother(James) also illigitimate. James had a middle name Lynch. James Lynch`s grandson took a DNA test and has found a common ancestor 6 generations back with the surname Lynch. But John has no male decendents and we wondered if there was any chance of finding out his parentage.

Hi Mary
Have you tried contacting the companies that do the DNA testing - in particular the ones that specialise in relationship and legal testing? They should be able to tell you what is possible.

I'm 90% certain that the answer to your question is yes if you follow the male line(s). As said above you should contact one the companies to be 100%.
-
Yes, but there is no male line.

My understanding is that you need an unbroken male line. If as you say, you have only a female line back you will not be able to use dna testing to prove a connection. have a look;- http://www.familytreedna.com/landing/paternal-maternal-test.aspx

Hi Youngtug.
Just had a look, thanks for posting it. It answers my question. In other words, the female decendents dont have a hope in h***.
Was hoping there was a minute chance, but see that ain`t so.

Yes, but there is no male line.
Sorry - misunderstood.
I don't know if tests are generally available, but I think mitochondrial DNA can be used to trace female lines.
-
You can trace a female line, but not back to a male.
-
This is where lockets containing baby curls and those heirloom mourning rings and miniature portraits made of, or containing, human hair come in handy to use as DNA samples.
-
So what it all boils down to, a female has no way of determining who her father is or vise versa.

I'm sure they can do paternity tests for girls as well as boys, so I think we must be missing something here. Perhaps you have to go back one generation at a time :-\
There is a lot of information on this site

there are companies that do paternity testing, they use different markers on the dna and the result is ;- most probably the father [99%] most unlikely [0%] but this is not of use for geanology.
