No record of anyone named McKinney in Roddey's 4th Alabama Cavalry Regt. The town of Nauvoo (not Narvoo) exists in Walker County just northwest of Jasper AL. A man named Wilson McKinney (or McKiney) served in Co. "H", Snodgrass' 55th Alabama Regt. His company was recruited in northeast Alabama.
Where did yo ufind a record of service for this man? Do you find him on the census in 1860?
