"Variant of Hermenegildo"
The name Herminio is commonly a male name from the "Spanish" origin.
Herminio is a masculine given name used in Spanish-speaking countries, with the accented Portuguese form Herminio (written HermÃnio in Portuguese) also in use in Portugal and Brazil. It is a shortened form of Hermenegildo, the Spanish continuation of the Germanic name borne by the Visigothic saint Hermenegild. The shorter form stands on its own as a given name rather than carrying a separate meaning.
The pronunciation of Herminio is her-MEE-nee-oh.
