All I have on James and Nancy Cameron is that they were both born in Scotland. James was naturalizedin 1813 and resided in Argyle around 1802. He may have been living with a sister. I believe she married Gilbert Robertson. They're burried in the churchyard at South Argyle. As far as Sarah Cameron, according to the Griffin Genealogy she was the daughter of Duncan & Margaret Griffin Cameron. I also have a daughter of James & Nancy Dow, Jeanette or Janet who married James W. Cameron. She was born ca 1809 and died march 6, 1894 and is in the Warrensburgh cemetery.Hope this helps.
