I love
Alice too, but I like it spelled
Alys (I saw it in a book). I know, I know, re-spelling classics, but I still think it's pretty.
I always try to be cautious of alternate spellings, mostly because my own name gets destroyed fairly often. Mostly I just ask people how they pronounce their name, because then they have the joy of explaining it to me instead of correcting me :o) But yes, I do tend to pronounce it in my head differently, usually.
