Are you referring to William Lynn who is one of the responders to post on this same subject. I believe the above William is dead. William has left behind, at the Library in Uniontown, copies of his Ancestry research. Also William I believe was part of the Andrew Lynn line. There are many living relatives of Andrew Lynn. If you were to have some Lynn male of your family take a DNA test at FamilytreeDNA you could then join with other Lynn's in the Andrew Lynn DNA group. If you are referring to some other William, you will want to take a DNA test to see which of the Lynn lines you belong to. There are at lest 4 or 5 different Lynn lines that passed through the Fayette co area. The above library also has much info regarding burial's at various cemetery's in the area.
