kt, I also found an Isaac Farris in the 1810 census from Washington Co., VA; also in 1820 an Isaac Faris in Hamilton Co., OH, Crosby Twp; and in the 1830 census an Isaac Faris in Laurel Co., KY. In the 1850 US Census for Clark Co, IL, Isaac Farris was 39 years old and a farmer from VA, his wife Catharine was 38 and from OH; Christina was 10; Elizabeth was 12; Samuel was 10 (these are all according to census data); Eliza was 8 and Mary was 1. Good luck in your search. Phyllis
