Hi Wombat.
Thanks for your response which is very interesting as Joseph Brewster (b1739 d17??) (do you know when he died?) was my 4x Great Grandfather.
As he was also your 5x Great Uncle, it follows that our common ancestor is therefore their father JONATHON BREWSTER (1698 - 1765) who married Ann Mafin in 1719 in Good Easter which I believe makes us 5th cousins.
According to my FT they had at least 7 children viz John(B1721), Ann(b1722), Martha(b1727), Tabitha(b1730), Jonathon(b1732), Edward(b1735) and Joseph(b1739)
Who are you descended from?
I have another three generations in my FT back to John Brewster c1590 who in 1625 married a Jane ?
Does this tie in with your tree?
Hope to hear from you sometime as I would like to continue this dialogue with you.
Best Regards,
