Hi, Karen. Stockley Donelson Peal was my maternal great-great grandfather. Most of what I know about his early life and history I learned from a book written by Jean Dennison about her Stroud/Dennison family history.
I did some research on my own back in 1992-1993 and came across some info from census records in TN and MS as well as his muster roll while in the 20th TN Army regiment during the Civil War.
Contact me if you're interested in what I know (or remember since I don't have access to my records at this time).
