Jean Louis Fontenot arrived in Mobile in 1719. He had 8 sons. They were given "dit" [nicknames] to distinguish which descendants came from which son. Philippe was d'St. Philippe (although I haven't run across any of his descendants who used the dit name)--but it was HIS son Joseph LaRose (married Madeliene Hayes) who started the LaRose "clan". I have heard also that it was because he had red hair. But that could easily have come from his earlier roots. The father(Jean Louis) carried the "dit" name "collin" which it seems came from HIS father as evidenced from his burial record from France in 1725 as "Joachaim Collin". Son Jean Pierre (who married Marie Francoise Lagrange) was known as "d'Cadet"---that it supposed to mean the youngest, which he was at the time. Jean Louis (fils)(married Marguerite Francoise Doucet) was known as "d'Debonnaire", which is supposed to mean "handsome". And then there is Joseph "Bellaire" and Henri "Bellevue". I am not sure of the origin of all these names, whether they have to do with where they were living or what. If you have researched the Fontenot's you know how many there were and how they all named their children the same---had to have something to tell them all apart. But I have to say I have never heard of the "Shadolots"---could these be descended from the one who went to Edgard? How far have you researched these? Would be interested to know more.
