Does [name_f]Rosalie[/name_f] work as a middle name for [name_f]Eleanora[/name_f]?
Yes, it’s very pretty! And so many rich nickname possibilities.
I love both of those names so much and they look wonderful next to each other. The only problem I have is that when I say it out loud, the two "r" sounds so close together make it seem a bit jumbled… but maybe it’s just my accent. It’s not a big deal. Go for it 
It sounds beautiful! The two “r” sounds are close together, but I don’t trip over them when I say over them out loud. Both names are elegant and sweet.
Very pretty.
I like it, though I think [name_f]Eleanor[/name_f] [name_f]Rosalie[/name_f] would win but just a hair for me.
