Emmilia is a female name.
Emmilia is a female form of Emil/Emilio or Aemilius. The Aemilians were one of the five most influential patrician families in ancient Rome.
Emmilia means “from the Aemilian family”. This in turn is derived from the Latin “aemulus”, which means “emulate”, “compete”. That is why Emmilia also has the meaning “the eager”, “the industrious” or “the ambitious”.
