I'd be happy to exchange information. My great great grandmother was Odille/Domitille Thiriac (c.1828 - 1888), who married Jeremiah Vincellette/Vanslette about 1848. They lived in Swanton. My great grandmother, Julia Vanslette was born at Swanton on February 8, 1857.
I have quite a bit of information on the Thiriac/Lafar line, but am always looking to add new information.
