Lamar is really knowledgeable. The other Boulet genealogy guru is my father, Loyd Boulet, a physician in Opelousas, LA. He wrote a book on it; however, it was self published and only a few copies are out there. He also did a presentation about the Boulet Family Lineage at the reunion in 1999 and has spoken at various conferences on Le Grand Derangement from a medical history standpoint ('a la Rats, Lice, and History).
