The name Josette is a girl's name of French origin meaning "Jehovah increases". Josette and is often added to lists like Soap Opera Baby Names and discussed in our forums with posts like "Names on NB that make you go WOW!".
From the experts:
One of the group of French 'ette'-ending names that emigrated to this country in the last century, though never as popular as some others, such as Claudette and Paulette--it did have a little six-year flurry here between 1967 and 1973. Josette may be feminine and flirty, but, given the choice, most parents today would prefer Josephine.
