I really, really like
Gillian, but only pronunced with a hard G as in Gilligan. I think Gilly's a sweet nickname.
Jillian can go away and stay that way. I always think of one of the girls who had a "Vote Bush or Die" shirt on during the election--she got mad when I told her she misspelled "and" on her shirt. :)
I like
Jill, but not
Jillian. And
Gillian (and Gilly) totally beats both.
