Has anyone with a male line back to Philip Nelson (of Rowley MA) had a Y-DNA analysis done? It would require a test for at least 37 markers to avoid hundreds of hits from very distant lines. A pattern match gives hope to someone who is looking for male-line documentation back to Philip Nelson, while a mismatch should discourage them from further research along that line, since it is very unlikely that they are a descendant if there is a 4 or more mis-match in Y-DNA markers. There are several Y-DNA patterns from the Brimfield MA Nelsons and one from the Yorktown VA (Thomas) Nelsons in the Family Tree Y-DNA database.
