Juliette!

My daughter is Rosemary (Rosemarie may go well with an Italian alst name?)

I figure she can go by Rosemary, Rosie, Rose, Mary, Rory, Romy

I think you should break the EJ/JE thing.

I like Cassandra from your list.

Helena from someone else's list.

Also, maybe Victoria, Veronia, Vanessa, Nina, Lucia or Luisa?

I really like Cassandra Ruth. Not too fussy. Not too common, but not strange either.
