I am actively researching two lines, both of which moved from Columbia County, New York, to Dunham and other towns in Missisquoi County, Lower Canada, possibly via other locations. My Humphrey family moved to the Dunham area about 1799-1806. Thomas and Eva (Schryver) Humphrey and some of their children, including Nicholas, Peter, Catharine, and Abraham made the move. My 3rd-gr-grandfather Nicholas Martin Humphrey was born in Dunham on 6 Dec 1806 to Nicholas and Margaret (Snyder) Humphrey. Nicholas Martin Humphrey married Sophia Van Allen (b 25 May 1810 NY), daughter of Andrew and Margaret (Diel) Van Allen, who were in Dunham at least 1825-1831. Nicholas and Sophia and possibly some of the others also lived in Upper Canada, but I have not found them there yet. I have searched the Dunham church and census records. Any additional information would be welcome.
