Enchanting Spanish Names

A bunch of Spanish names I collected from people I've met. Some are a bit more on the unusual side

Mathias 

A pretty smoosh name predominantly used by Italian Catholics.

 The meaning of Maria is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Annamaria

Amada is an unusual Spanish name that's becoming more famous thanks to Ryan Gosling and Eva Mendes, who named their second daughter Amada Lee and their first Esmeralda Amada. Amada was also the name of two characters played by Mendes and, not coincidentally, her grandmother's name.  In 2015, it was used for only 21 girls while brother name Amado was used for twice as many girls, but we predict the name will become more popular thanks to its new star power. Related names include the Latin saints' name Amatus, the musical Amadeo, and even Amy and Amanda.
