"Variant of Emygdius"
The name Emigdio is commonly a male name from the "Spanish" origin.
Emigdio is the Spanish form of the Latin name Emygdius, borne by a bishop of Ascoli Piceno who was martyred in the early fourth century. The same name appears in Italian as Emidio and in Portuguese as Emidio with an accent on the i. The meaning of the Latin name itself is not established, so the Spanish name is described by its lineage rather than by a translation.
The pronunciation of Emigdio is eh-MIG-dee-oh.
