I have just seen some info written by my great grandmother on this line of ancestry.Here is what it has...
Benoit Baron Bayard was the son of Benoit Baron Bayard and Marie Hortence Boutte.He married Josephine Babineaux who was the daughter of Joseph David Babineaux and Rosalie Segura.
Benoit Baron Bayard and wife, Josephine Babineaux had a son named....(You guessed it!) Benoit Baron Bayard.He married Euphemie DeRoven (Could be DeRouen), who was the daughter of Alexis DeRoven and Marie Celinie Hebert.
These Bayards were living in New Iberia in the mid 1800's. Any connections?
