Hi David, I just found this board as I'm new to this. I have a Nathaniel Hartford, b.1776 (of Dover, NH in the 1820 Census). I've been trying to trace him but almost gave up until I decided to join the computer world. Is he the Nathaniel you have? Mine married Dec 31, 1800 in Belfast, both of Belfast, Abigail Fowler, b.1783 of Bucksport. He d. 1854and she in 1864, both buried in Swanville. I do hope we have the same family. I was so glad to see your info and hope to hear from you.
