Laurel,
Oliver and
Hollis would all have that open "au" sound in them.
So that eliminates the original combo, imo.
And as for
Avery, I don't find the name very female, it's OK, but
Oliver and
Avery sound so... similar, because of the same stress, I guess.
I find
Hollis better than
Avery but
Ivy even prettier.
First combo.
