Wdyt of this name? DH and I both love it, I think it's beautiful and also literary- from Ivanhoe, and I much prefer it to the more common, although Biblical, Rebecca. I also love Rowan on a boy, but I'm tired of hearing about it being used on a girl. Rowena is a much more feminine form imho.
Some combos:
Rowena Elizabeth- love this
Rowena Grace
any other suggestions? Thanks!
