I have a DNA question that I wonder if someone can answer. Here is the scenario. Great Grandparents Parents Sons Grandsons PARENTS - A couple has 15 children, 10 boys and 5 girls. SONS - Two of the boys both become fathers. Their sons, of course, are first cousins. I will call them Son A and Son B. GRANDSONS - 56 years later and Son A now suspects that his father is his uncle and that his cousin's (Son B) father is also his father. Question here is since all these males are coming straight down the same line, would a DNA test actually show if Son A and Son B share the same father or would it be flawed since all are from the same male line? Son A and Son B have the same great grandfathers since their "fathers" were brothers. Basically, there is a suspicion that the two first cousins may, in fact, be half brothers.

George, I would suggest that you ask this question on one of the literally hundreds of mailing lists that are specific to DNA research. Almost every surname has one dedicated to it. You can find the one you need by going to: http://lists.rootsweb.com/ Type in DNA XXXXX (surname) in the search box. Hope this helps, Karima ----- Original Message ----- From: "George E.

My thanks to all those that responded. Karima, using that link I did up finding a site that can do the DNA to test to see if cousins are actually siblings or half siblings. However, the test is over $1500. On that basis, I think I will be satisfied to know that my cousin is my cousin rather than my half brother. After that we share the same line going back.
