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