I found a William P. Martin in the 1860 Floyd County, Georgia Census. I have listed below what I found: James N. Cooper 48 M Warehouse & Corn(?) 2000 1000 SC Sarah C. Cooper 38 F Domestic Tenn. William P. Martin 15 M Printer Ala. John D. Bradford 4 M Ala. I think the above is my William P. Martin and he is listed as living with James N. & Sarah C. Cooper. My William P. Martin(unknown birth date) married Sarah A. Martin 25 November 1869 in Clarke County Georgia and his wife, Sarah A. Mobley died March 1, 1920 in Madison County, Georgia, but I don't know of a death date for William. If this looks familiar to anyone, and you can help me make a match, please email me at nbedell@negia.net.
