I am very interested in the Gerrit Dorland listed by Barbara Barth as living in Northumberland Co., PA, for I think it likely that I am descended from John Darlin, listed in the 1800 census for Northumberland Co. and presumed to be one of the children of Gerrit. There are problems that need to be resolved that I hope someone can help with.
1. I do not know why Barth's book states that Gerrit was living with his son, Gerrit, at the time of the 1800 Northumberland census.There was only one adult male in the household in 1800, and this must have been Gerrit, Jr.There were two adult males in the home of David, Sr. that year, and one of these may have been Gerrit, Sr.
2. There is a problem in Barth's book in assuming that David, Jr. is the David who moved to Fredonia, NY.In the 1810 Northumberland census he appears to be married, with two children under 10 (one girl and one boy).If he moved to Fredonia, we would have to assume that his first wife died and that he later married Ann Pierce.My own guess is that this is the Durlin who moved to Westmoreland Co., PA and had a son, Alexander, and a daughter, Catherine, whose birth dates are known to be 1806 and 1805, respectively.Alexander in turn had a son named David.
Barth's book also mentions another David (p. 180), and says he was possibly the youngest son of Lawrence.His children are named (credited to me in the footnote).My own view is that this David was the son of John, found in Butler Co., PA tax records a short time after 1800.Lawrence remained in Northumberland Co. several more years and appears there in the 1820 census.
I am interested in what further light anyone might be able to shed on this line.
