His probable Civil War service was in Company B, 38th Mississippi Cavalry. He spent a few month in Alton prison.
His occupation was thought to be doctor. I can't find any information about his birth or his parents. Nor can I find any record of him after the Civil War. Sarah and their son Calvin are living with her sister in 1870. I can't find anything to indicate that he did not survive the Civil War.
If anyone has any information, please share. I have lots of information about his descendants that I will be glad to share.
