I just saw your message. I have a Warren Griffing b. 1797 on Long Island. He was the son of Peter Warren Griffing b. 12 April 1780 Southold, Long Island and mother Mary Brady who d. 31 Jan 1855. I'm showing that Warren had a brother named Austin, but I have nothing else on these two. I hope this helps. There are some similarities there that you might want to follow up on.
Good luck, Patrick Collier firstname.lastname@example.org
