I used to like the sound of
Paige until I really focused on its meaning and didn't care for it. I mean, I realize
Brooke (brook) is a noun and a nature reference, however, it's picturesque and tranquil and has a lovely sound and represents all of these good associations to me so I'd go with that. Of your combos, I like
Brooke Estella best, however, I'd recommend
Brooke Louise Elisabeth to incorporate
Louise and
Elsa or even
Elsa "
Brooke"
Louise although I know some people don't like going by the mn.
