Finding Christopher and family in the 1810 census for Pharsalia was a major step, but has yet to lead to the solution. We know they were there in 1810  and Christopher was there to witness a land sale in August 1802. but we do not know when they got there and from where. Perhaps they came directly from Stonington CT or elsewhere in CT. Perhaps there was an intermediate stop somewhere in NY.

Christopher was 36 in 1810 and therefore 26 in 1800 . With a wife, one male child under 10 and two  daughters under 10 they should be separately listed in the 1800 census. But no one has found them, yet.

http://www.rootsweb.com/~nychenan/pharhist.htm has a wonderful history of the early years of Pharsalia from which I have taken major portions and added emphasis to show the extent of the Stonington connection.
