I have always liked this name, and to a Finn, the name sounds literally joyful, as 'ilo' is the Finnish word for 'joy', and this name actually happens to tranlate into a little somthing like ''as a joy'' in Finnish. Not that this name is considered a word in Finnish. It's a very pretty name, although I must confess that I'm not sure how well it suits women past the age of 25. If any English-speaker wants to use it, I would recommend you to keep the stress on the first syllable, otherwise it sounds like there's a ghetto pronunciation of 'loner' in there. :-)
Also possibly derived from the Finnish word iloinen, happy.

There is a very pretty song called Ilona by the musical artist Amethystium.

Well in Greece the name Ilona is very rare, nearly doesn't exist... my mother has an Hungarian classmate named Ilona and so she decided to name me Ilona too... till my 16 years old I hated my name cause no one could pronounce it and everyone asked me if I was from another land... but now I feel very special and unique as my name! I find out that it means light and combine it with my final project of my college. I'm writing about wooden jewlery (rings, bracelets..) and I'm inspired by my name. light: comes out from sun, whose shape is round, is the domain planet of jewell makers and contains all wooden colours, it gives life to everything! Without the sun there would be no trees... so everything is a circle bound all together! I love my name (and my project!) thanx mommy! :-D.
