I can't remember how far the books go back at the Catahoula Parish Court house... hove you called the Clerk of Courts office there?? They are very helpful and would be able to ell you a few basics. I won't be going up there for a while or I'd look for you! I believe those records have been microfilmed. Have you looked at those?
I'd love to help you if I can... and if you aren't able to find out more, I'd be happy to look next time I'm up that way! Let me know how you fair, ok?
