Rowena :/ Like... the letters are there but the sound isn't. For example, I could sort of understand Rosie as a nickname for Rowena because of the 'ro' sound but there's no corresponding noise in Rowena that matches Ren other than 'r'.
I like Rowena Lucy but feel like it's a bit much with Pearl on the end. Maybe it's the rhythm of the two short names? Rowena Lucy Margaret (with the meaning of pearl) is nice too :)
Depends on pronunciation, methinks. Am I right in thinking that a lot of North Americans pronounce Rowena as ro-WEN-uh? If so, the nn Ren is feasible and cute :) However, if it's pronounced like how I would say it, ro-WEEN-uh... not so much.
Rowena Lucy Pearl is ok, but I think with some rejigging with some other names it could be better :)
I think Ren works. Cute!
Best of luck!
I just found out the correct pronunciation is "roe-WEEE-nuh" which just ruins the name for me. I've always said "ruh-WEN-uh". Now all I can think of is some guy taking a really long leak. :/
