Hello, Yes, I have a James and a John in Clark County, but not in 1820. The ones I have information for are in the 1850 census and are sons of Sylvester (Samuel) and Mary Farris. James was born in 1847 and John was born in 1844. In fact, I believe that Mr. Crabtree sent you the same info which I have. In the census info I have for 1820 in Illinois there are no James nor Johns Farris/Faris/Ferris listed for Clark County. In 1830 there is a Thomas mentioned in Clark Co., but no James nor John, although there is a James listed in Edgar Co. which is immediately adjacent North of Clark Co. And in the 1840 Census, Isaac, Silvester, and William are mentioned in Clark Co. Isaac's family and Sylvester's family members are listed in the 1850 census.
