In French, fruity names plus spices names are a trend, small, but a trend. They are known and used since the French Revolution and in some cases they coincide with saints' names (as Pomme very close to the saint's name Pome), but lately this names are appearing more and more in naming boards (I noticed Cerise, Prune and Cannelle in a lot of discussions by mothers-to-be).
Here you have an article about the most used:http://www.notrefamille.com/v2/editorial-dossiers/les-prenoms-de-fruits.asp
In Catalan, Mirtil ("bilberry") and Gerd ("raspberry") are used, but they are little-known fruits and they coincide with a mythological name and a German name, which means that they are more acceptable to most of the people. But it is clear its intention as fruit names because often the siblings have also names coming from words: Gavina ("gull"), Isard ("chamois"), Mel ("honey"), Brot ("shoot"), Acant ("Bear's Breeches")...
In Spanish, the use of fruity names is unknown (to my knowledge) unlike other names coming from nature words (Lluvia, Luna, Arena...).
