Genaro

Genaro is a Spanish form of the Latin name Januarius, meaning of January. The month name is connected with Janus, the Roman god associated with doorways and beginnings. That older background explains the calendar connection, while later Christian use gave the name a different religious focus.

Saint Januarius, known in Italian as San Gennaro, is especially associated with Naples. The tradition surrounding his relics helped preserve the wider name family. Genaro and Jenaro are Spanish spelling choices, while Italian Gennaro has a different opening sound and a double n. A family choosing Genaro may be honoring the saint, a relative, or the month, with those personal connections adding context to the same Latin-derived history.
