Trying to find parents and siblings of Richard C. Turnbill b.1839 in Knox Couty, TN d.1915 Loudon County, TN. Lived most of his life in Roane County. Also , does anyone know where the Philidelphia P.O. was located in the late 1800s? Was it in what is still the town of Philidelphia, TN? Any help is appreciated. Shirley
