Jim - thanks so much for responding. Here is what I have dug up so far:

⇒ 1861 - Joined the Confederate army, entered CSA as Lieutenant Colonel on 7/3/1861
⇒ Unit: F & S, 3rd Reg't Cav, 8th Div, Missouri State Guard
⇒ Commanding Officers: Colonel R.L.Y.Peyton, Major W. S. Taylor, Captain D.W. Williams

See a copy of his service record here: http://wwwamericana.com/MartinWhite.html

He didn't last long - went in July 1861, was reassigned in August and then died in April of 1862.
