Hi Lesanne,
I've not looked at the boards for ages, so sorry I didn't see your post before now.
Yes, still been digging away at the Hawkins family. Managed to find the will of the uncle of the John Hawkins who married Mary Dewe and from that learned that John's father was also named John. His uncle's name was William Hawkins, of Mortlake, who died in 1677 apparently aged 53. I've found records of a John b.1621, William b.1624, Mary b.1622, Margaret b.1623 and Thomas b.1625 born to William Hawkins at Saint Margaret, Westminster, London, which could be them. The William who died in 1677 was buried at Mortlake, and his memorial stone has the coat of arms based on the one that was granted to Sir John Hawkins, though without the additional crest that would only have been allowed to be used by direct descendents of Sir John, rather than his family. This would suggest his father might have been the William Hawkins, son of Sir John’s brother William, as the coat of arms would match, as well as the dates. But that remains just a theory until I can figure out a way to prove who the William Hawkins who had children in Westminster in the 1620s was. Unfortunately there are several Hawkins families in that area at the time so difficult to pin the right one down.
Would be interested to learn more about the Mary Dewe/Banks line.
