DNA testing question
Does anyone know if DNA testing can determine if descendants of a particular great, great grandfather are also descendants of either his first or second wife?
Over the years I have made contact with a number of Meehan relatives.All of us are descendants of the same great, great grandfather Meehan, who came to the United States from County Sligo, Ireland, in the 1860s.There are indications that he may have had two wives and that some of us may be descendants of he and his first wife and other of he and his second wife.
Thanks for any info on this question.
