I note that the Family Tree DNA public DNA website for the Martin family shows that a male Y chromosome DNA donor who shows his lineage back to Valentine Martin (born about 1709/1710; an apparent son of Martin Martin and Sarah Hix/Hixe) is a good "Y DNA match" to another male Y DNA donor who shows his lineage back to the immigrant George Martin (born 1630s). I see from various posts that the Kennon family married a Martin descendant of the Immigrant George Martin. There has been some debate over the years as to whether or not Martin Martin was a member of that same overall George Martin family....but assuming that the referenced male Martin DNA donors have their ancestries properly stated, it now appears that they were, in fact, related.
Per some researchers (but not proven by me), the father of Martin Martin was the George Martin (born 1650s) who married Susannah West, and the father of that George Martin was the Immigrant George Martin (born 1630s) who married Winifred Lewis. Comments?
