Io is a guilty pleasure for me. I love it, but it's not very practical.
I once read a Russian short story where (if I recall after 40 years) a young woman is named
Io ("EE-o"). She's in love with
Rudolf /
Rudolph and somehow starts calling herself (or them as a couple?) Rudophio / Rudolfio. I think it was written in the 1920s so it greatly preceeds the Bennifer / TomKat / Billary / Brangelina, etc., phenomenon. Anyway, it always stuck with me as a cool name.
Io Ruxandra? :0)
