Don't know if this will help, but in my Alleman search I ran across:Onesime Alleman b. 1826, mar. 1845 Elmire Champagne. Parents of Onesime: Balthazar Charles & Clara Trahan. I also link to Granger & Stelly! My Alleman link is Onesime's brother Joseph who Married Melanie Cormier-their daughter Adelphilia mar. 1907 Louis Thibodeaux.There are Douguets interlinked with Alleman & Thibodeaux. I have not gone farther back than Balthazar.
