I love
Elias Henry, it's a gorgeous combo. :)
I have always disliked
Lauren, I guess since it's overuse in the 1990s. :-/ But between
Lauren Grace and
Lauren Rose, I'd pick
Rose. Otherwise,
Audrey &
Lauren's middle names both mean "grace" but
Olivia's does not. Picky, eh? :b Other than that, I think
Olivia and
Audrey sound lovely together but
Lauren sticks out as less classy/classic/old-fashioned to me. Though they are all similar in popularity. Maybe
Olivia,
Audrey +
Emma or
Isabel (I like them all starting with vowels) or maybe
Laura /
Laurel.
