I have a very large Fontenot database. Recently, I printed 3,000 Fontenot family groups sheets. If you can tell me who your Fontenot ancestors were before 1909, I can probably send you your direct line. I say 1909, because the published Catholic Church records I use begin in 1750 and end with the year 1909.
After I entered records from 1750-1840, I stopped routinely entering Fontenots (Guillorys, Vidrines, etc.) I now enter Fontenots (etc.) when the need arises to complete a link.
I used to give away entire family files, but since I hope to publish my reserch, I don't do that anymore. I do however, help people who want to do their own research, and I do give them their direct line of descent if I have it or can find it. At the same time, it enriches my database, like adding a new blood line.
