I must first say that when I first heard this name (in 5th grade, when she was in 7th grade at my school) and she became one of my sister's best friends, I thought it was a really cool name. And - gasp! - I still almost like it. I don't know why, because usually I think replacing an "i" with a "y" kills the name, but since Smith is not used often anyway, especially for girls, I kind of like it.
WDYT? I know most people are going to think it's atrocious, but still!
