Lynne, Check the 1850-1880 and 1900 Pickens co, AL census for O.L. McKinstry. The 1850 and 1880 are on-line now.e-mail me if you need address. There was also another J.A. McKinstry in the 42nd AL Inf but don't know where he from in AL. This should give you a good start. Let me know e-mail if I can help.
