In my 22 years in the Mobile area, I never read or heard much about "known" decoy carvers from that area.
I'm sure there had to be someone carving down there given the long history of waterfowling the Mobile-Tensaw Delta, Mobile Bay & Mississippi Sound.
About the most "historic" decoys I ever saw in shops were old paper mache and a scant few Mason/Mason-type factory wooden decoys.
Bayou la Batre had a reputation as a sporting destination for duck hunting at the turn of the century, before the hotels and casinos were destroyed by a hurricane in the early 20's, had to be someone carving down there.
I also heard that the visitors center/museum in either Orange Beach or Gulf Shores has photos of duck hunting Little Lagoon & lower Perdido Bay back in the 30-50s. From what I heard from a member of an old Orange Beach family, the duck hunting on Perdido Bay back then was fantastic for scaup, redheads and cans. Actually, it's still decent now if you can find a place to shoot that is outside safety zones.
my 2 cents.
