I love these names, and this combination in particular. [name]How[/name] does it sound to all of you? 
I love the strong and vintage [name]Eleanor[/name] and I like the Welsh [name]Rhonwen[/name] too but the back-to-back r’s hinder the flow of the name a bit for me. If you don’t mind it, I think the combo is unusual and distinctive.
Agreed with pp - [name]Eleanor[/name] [name]Bronwen[/name]?
Agreed! I quite like it myself
I like both names and think they are good together-- the double is a little difficult but I don’t think it should be a showstopper.
