Before I begin with my question, I just want to say that I have not exhausted all of the records available to find an answer to my question. At the moment, I haven't been able to do very much research on this mysterious ancestor. Of course, of the little information I have found so far, the information about the year born and possible parents are conflicting.
Of course, I am wondering how feasible is DNA testing would be in determining the parents of my ancestor. My ancestor and his possible parents have been dead for several decades, but some of my ancestor's descendants are still alive. I do not know if there any male descendants of the possible father that are still alive. Would a y-DNA test be feasible to determine a possible paternal ancestor going back two or more generations?
Please forgive me if my question is unclear.
