Ms. Jennifer, I can't find him in Booth's Record of Louisiana Confederate Soldiers or in the online Louisiana Confederate pension application index. Is it possible he served under another name? This is not 100% proof positive he didn't serve. I have a 3rd great-uncle who has no record of his service except for being named on reunion list.
