----I am not related to the Haas, but I reside in Opelousas, and historical genealogy is a hobby of mine. I have done considerable research into the descendants of Captain Samuel Haas. Below are a couple of URLs with brief excerpts which are somewhat related to your inquiry or may provide some leads.
