Co I - Capt Nathaniel J.W. LeCato's Co [Cavalry]; enlisted Sept 11, 1861, for three years; disbanded per S.O. No. 20, A&IGO, dated January 25, 1862
It is very possible that he served in the 39th Va Inf {Cav unit] and then in Mosby's unit after January 1862.
I am guessing that he is probably the son of Lorenzo D. and Elizabeth A. Walker of Fauquier County, Virginia, born about 1847.
