Alan,

I've had an opportunity to do just a little backtracking on my research on Col. Martin. Here is what I have found so far:

Obituary in a Pickens County newspaper
"Died - Col. Alburto Martin, 11/30/1879. Born 1830. Graduate of the University of Alabama. Resided here as a young man."

Now, that will hopefully lead me to where I located information on his service, and that of his brother. There was a book published about that same time period that lists what happened to each of the graduates of the University. If living, the graduate themselves wrote their own bio. Anytime I see that a soldier was a University graduate, I consult that book. I don't remember the title off the top of my head, but it is in the library here at UAB. It has been removed from the shelves, so you have to ask for it, and they send somebody to the basement storage to get it!
