Benou is the French translation for the Egyptian god Benu or Bennu,
Phoenix was the name in Greek. But if Benou is a surname, I think that it comes from the toponyme Benou, in the Pyrenes.I haven't here informations about the etymology of Benou, but it seems an adaptation to French spelling of the Occitan and Catalan of the North pronounce of the -O (e. g. Canigou for Canigó, in Catalan); then, the origin might be
Benó.
Mer is "sea" in French.
Gondree: Is it Gondrée (with written stress) or is it pronounced gron-DEE? Because if it is the second possibility, the origin might be the French surname Gondry, from the
German personal name Gundric (grund, "fight", and ric, "ruler, power"). If it is Gondrée, I don't know the origin.
Godet is a French surname which comes from the
German personal name Gode/Goddes (from god), directly or throught other old names as Godard.
Degas is a French surname meaning "from Gas". Gas is a toponyme meaning "land not cultivated" and nowadays they still exist the towns Gas (Eure-et-Loire) et Gast (Calvados).
I don't find anything about
