Looking for info on Chileon A. Cox, (b. 1810-1820 in Champaign County, Ohio). He married Mary W. Baker (b. 1810-1820 in Spencer, New York) on 9/3/1939 in Champaign County. He is listed in the 1840 census but I can find him nowhere else. They had a at least one child, Sarah L. Cox (b. 7/9/1841). She married Jonathan W. Smith on 1/4/1860 in Logan County, Ohio. She died on 4/4/1921 in Alton, Madison County, Illinois.
Anything you can share is greatly appreciated. I have most of Sarah's descendents.
