I have a copy of a picture of a Civil war marker taken at Princeton Rd. Austin Springs, Washington Co. Tn. listing the name as Francis M. Lawson, Co. H. 13 Tn. Cav. My Great grandfather bore the same name and I have no info as to where he is buried and even if he was in the Civil war. Could this be him? He hailed from Madison co. N.C. and supposed to have died in 1897. Help please!
