I'm descended from a Samuel Campbell in Franklin County, but he was born about 1854 and married Eliza Perdue. I don't have definite information on his parents, but have a theory that his parents were John Campbell and Nancy Dunn. In 1860 Peter (7 yrs old) and Susan A Campbell (10 yrs old) were living with Dieherson (or Dickerson) Dunn. There's a Franklin marriage record for a John Campbell and Nancy Dunn in 1849. There's another marriage record for Samuel Hodges and Ann Campbell, daughter of John and Nancy Campbell. My Samuel Campbell had the middle initial P and named his first son Peter William Campbell.
