The Cowan YDNA project includes two kits that match more closely to each other (9.5% dissimilarity) than to other kits in the project. Both kits are in the R1b1 haplogroup. The level of dissimilarity in their YDNA suggests that they probably share a relatively recent common ancestor. One kit traces to Isaac Coen who died in Wetzel County, WV in 1864. The other kit provides no lineage data and so can not be commented on further. Ancestry Public Member Trees show numerous lineages for an Issac Coen. Most give his Birth as c1785  and a DOD of 1864. There is substantial variation in the identity of the parents in these lineages. Most give his mother as "Elizabeth", last name not known, but there are other candidates listed. His father is variously identified as Isaac, Isaac Moses, Moses, Peter William, James. This may indicate that data for different Isaac Coen's have been merged in these lineages.
