It was interesting to see that Napthali is my 4th great grandfather as well. My line goes through his son Josephus
who married Jane Chandler June 9, 1816 and they had 8 children, with James Simonson being my 2nd greatgrandfather.
Napthali married Phoebe Foredyce 25 Jan 1790. He died in 1803 . His father was Caleb, who married Elizabeth Mills. Caleb had 4 wives, but we assume that Elizabeth was Napthali's mother.(Her dates are May 1, 1726 in Bridgewater, Plymouth Massachusetts, to March 2, 1807 in Morris,Washington, Pennsylvania)
This is the note that I have in my family tree from the family Bible:
Moved to Washington County Pennsylvania 1792. Believed to be drowned at sea off the coast of South Carolina in a great storm in the fall of 1803. Probably the brother of Jacob Lindley the first president of Ohio University.
