Hi My mother was a Pourciau from Pointe Coupee, La. so I have extensive Pourciau information. I worked my way back to abt 1700, and am slowly working my way back to current, so I don't have all of the info to help you, but can get you started. Most of the Pourciau's were Catholic and therefore the details of their lives are recorded in the "Diocese of Baton Rouge Catholic Church Records". You can check your local library to see if these 18 volumes are on hand, or I can give you nfo on how to get them. Anyway; Marie Thalia Pourciau born 08-06-1860 to Savinien Pourciau & Evelina Saizan,of Pointe Coupee Parish, across theMississipppi River from Baton Rouge.She married Louis Vallet 05-01-1880, in the church, but there was probably a civil marriage prior to 05-1880. He was the son of Desire Vallet (deceased at this marriage) & Celestine Longlot (not sure of this surname). I have little on Savinien Pourciau & spouse and nothing on Vallet. I do know Sav's parents were Jean Baptiste Pourciau & Marie Euphrosine Chenevert and I belv he was born abt 1812. Jean Baptiste & Euphrosine are my gggg-grand-parents. Louis & Thalie(written diff 3times) also had Celestine Amanda Valet born 02-01-1880 & Evelina Dorothee Valet born 03-04-1890. Is this the same family?
