What does Nicolás mean?
The Spanish form of Nicholas, from the Greek Nikolaos, combining nike 'victory' and laos 'people'. Popularized by Saint Nicholas of Myra, the 4th-century bishop who became the basis for Santa Claus.
What does Gael mean?
A name of disputed origin, now very popular in Spanish-speaking countries (notably through actor Gael García Bernal). It is usually tied to Brittany, either as a short form of the Breton Gwenael (gwenn 'white, blessed' + hael 'generous') or to the Gaels, the Celtic peoples. No single etymology is firmly established.
