megan,
I was thinking...it might help you to research Mr. Brault's work. He is a published author on Breau genealogy & is a tremendous resource in this lineage. He is one of the few people who i take at his word when he calls a spade a spade (genealogically speaking of course). The only reason i suggested that i might be able to help you (earlier in the thread) is that i have one of his publications!
Good luck & best wishes...
