The name Toula is a girl's name of Greek origin meaning "light". Toula and is often added to user-created lists like Futuristic Female Names and discussed in our forums with posts like "CAF (Uncommon Names)".
From the experts:
Toula came to light as the name of the heroine of "My Big Fat Greek Wedding," short for Fotoula, a feminine version of Fotis or Fotios which means light. Toula is cute -- and indeed can be used as a short form of many feminine Greek names -- but it's hard to imagine Fotoula making it in the U.S. The multiethnic Tula may be a better way to go.
