"Variant of Beau"
The name Beaux is commonly a unisex name from the "French" origin.
Beaux is the French plural form of beau, the word for handsome or beautiful, and English speakers use it as a variant spelling of the given name Beau. The final x is the French plural marker rather than an English phonetic addition, and in English the two spellings are pronounced the same way.
Beau means "Handsome".
The pronunciation of Beaux is BOH.
