Well according to Illyana Rasputin's Marvel wikia pages the name means:
http://marvel.wikia.com/wiki/Illyana_Rasputina_(Earth-616)
"Ilyana" is actually the Bulgarian and Serb feminine of the masculine name "
Ilya". English equivalents of the name "
Ilya" are "
Elijah", "
Elias" and "
Elliot". In Russian language, the name "Ilyana" doesn't exist at all.
I'm not 100% sure if the name isn't used in Russia but here's the Illyana submitted name:

There's a thread about the meaning of this name here:

So yeah, I'm pretty sure it's the feminine version of
Ilya which means "My God Is
Yahweh".
Hope this helped.
