Descendants of Willem Davidszen & Helena Aards
If you are a descendant of Willem Davidszen & Helena Aards (17th century Dutch settlers at Flatlands, Long Island) in the direct patrineal lineage and you were submitted to a Y-DNA test (or you know someone who did), please contact me.
I try to solve a problem where genealogy fails: finding the MRCA of three Williamson lineages that are genetically related. Knowing the haplogroup of Willem Davidszen's descendants would be most helpful.
