ok wait does the first syllable rhyme with star or more? if it's like star, that's a tough one, because most of the spellings make it look like it's supposed to be
Marie...
Marrie? No. Mawrie? Mahrie? Mahry? Oh dear. Oh!
Mari! yes, I like that.
If it's like the male name Maury (like Povich) then I think Maurie would work well. Or Morrie! Cute. Morrey? hm. Morrie is sweeter, but Morrey is more unisexy-chic.
