I am also a direct descendant of Raimon Vessiere of Arkansas Post AR.I also have a lot of info on the line, but I have his wife as Jacinta Manuela de Torres of the Kingdom of New Mexico.I have that LaRose was a nickname that eventually stuck.His son Francois sometimes went by Vessiere and sometimes by LaRose and some records show both names.
Raimond Vessiere was a native of Falaise in Normandy and a wheelwright by occupation.He left France to come to New Orleans in 1756.His parents were Augustin Vessiere and Cecile Benoist (this was on the record of his immagration).
I do not have the name of the wife of Francois - possibly he was married more than once.One record has Mary and another has Elizabeth.Do you have any info on who she is?
I have more info if needed. Susan Fullbright email@example.com
