Here are a few possibilities, depending on how you want to emphasize certain sounds:
* Αιμιλία (Aimilia): This is probably the closest and most common transliteration.
* Εμιλία (Emilia): This uses the "E" which can be pronounced similarly in some dialects.
The best option depends on the context and personal preference. Aimilia is generally preferred for its accuracy in representing the sounds.
