Your Pedron bunch associated repeatedly in North Louisiana and South Arkansas beginning in mid-1800s with my LaBeff line which married into the Marks (Marx), Peveto, and Fogle lines from South Louisiana:
(1) You probably found Francis and Victor Pedron in the 1860 census of Ouachita Co.,Ark living among a bunch of LaBiff (sp), Peveto, and Fogle families. Also:
(2) Copied from The Muster roll of Company "B", 33rd Arkansas regiment. A note on the bottom of the ledger sheet says: "87 men. July 21-22, Delhi, La. thence to Camp Taylor on Boeff river Left here August 4, Marched to Little Rock reaching there on the 23rd. Camp Pirce-- remained here until August 31."
