I think the main appeal of
Isabella is the -bella part as are its nicknames
Belle and
Bella so I guess that's why
Isadora isn't more common.
Dora is not very fashionable at the moment.
As for
Arabella I think it reminds peopleof "arable".
I'm surprised about
Nicole as well. Some celeb actually named her daughter
Nicole Elizabeth which I find very 80s dated. I wonder why people didn't turn to
Nicola,
Nikola or
Nicolette.
Agree about
Jennifer.
I think
Ashley still sounds fresh to most people. I think many parents wanted to use
Madison but were scared off by its popularity and thought they were being creative by using
Addison. uhm yeah :P
argh I'm surprised about
Gemma and especially
Jemma as well. They are much nicer than
Emma if you ask me. I also wonder about
Jillian and
Gillian which are close to
Lillian.
