Thanks for the information. Dr. Miles W. Folkes was my GG grandfather. It seems he was born in Warren County (Vicksburg) Mississippi. In the 1850 census, he appears in Warren County as a student at the age of 20.
He served in the confederate army as a physician and druggist in Louisiana. He appears in the 1870 census as a physician in Calhoun County Mississippi. His son, James Duncan Folkes was living him in 1870. Sometime after 1870, Miles W. and James D. moved to Upshur county Texas. In the 1880 census, Miles W. is listed as grocer.
Miles W. Folkes appears to be related to the descendants of William Folkes who immigrated from England to North Carolina in the late 1700s. William Folkes had several sons who moved to Mississippi around Warren county. There are a few Miles Folkes in various records so it seems to have been a common family name.
I have not been able to find Dr. Miles W. Folkes' father so I don't have the definitive connection to the William Folkes family. If anyone has any clues, please let me know.
