Nicholas is of Greek origin, derived from the Greek word 'nikē', which means victory. It was popularized by Saint Nicholas, who was known for his kindness and generosity. Over time, the name has evolved into its present form in various languages: Nicolas in French, Nicolaas in Dutch, Nicolás in Spanish, and Niklas or Klaus in German. The most well-known variant of this name is perhaps Santa Claus, a figure inspired by Saint Nicholas himself.
"The name Nichlos experienced a peak in popularity around the late 70s to mid-90s, with a significant spike in 1981 and another in 1996."
