Hi Nancy: I, too, am looking for a Cox in Coal County. Cile Richard Cox was born in 1848 in Knox Co,TN and died in 1902 in Coalgate, Coal Co, Ok. His 3rd wife was Mary Susan Kimbrough. It is said his father was Richard Matthew Cox who was born in Knox Co.,Tn about 1822. In 1860, at the age of 12, Cile was living with William Cooley in Pike Co.,AR with his brother, Matthew Alonzo Cox(1849-1918). If you find anything on this family, please let me know and I'll be on the lookout for Cora Cox.
