Actually I have no further information on my Pierre Berard except that he was married to Marie Fortin. The Mississippi thing sounds very reasonable as the Berard family that I know settled in Cecilia, Louisiana which is the bayou country of Louisiana. Much of the French Acadians came down the Mississippi and settled on the Bayou Teche.
On another note, are you any relation to Joe Gilchrist Family of Oakdale, La. Or maybe Lula Gilchrist his daughter ? Joe was my ggrandfather on my fathers side and Lula was my grandmother. I have no information on them except that they were probably Irish/Scottish.
