Amy Margaret is surprisingly hard to pronounce, and I don't enjoy
Amy or
Monroe as a given name.
Margaret is good, though.
Anne ... well, I must declare my interest! I'm sure I'd like it a lot, even if it hadn't been mine.
Susan lacks pizazz, but the rhythm of the three together is fine, which it wouldn't have been if
Susan had been replaced by, say,
Susannah,
Suzanne or
Suzette; plus, both
Susannah and
Suzanne, though I prefer them to
Susan, have such prominent
Anne sounds that they wouldn't work.
Eleanor is timelessly beautiful.
