Emilia, the lovely feminine form of the Roman clan name Aemilius, is rising as an Emily/Amelia alternative, now at Number 268. Its one problem is that it sounds like and is often seen as interchangeable with Amelia, which has a different root and meaning.
Emilia also has Shakespearean appeal as the wife of Iago and confidante of Desdemona in Othello. In modern pop culture, Emilia is the name of the main character in The Princess Diaries.
Emilia is currently enjoying high popularity across some diverse cultures-- it's Number 13 in Scotland, Number 16 in Chile and Number 20 in Austria.
