Hmm...
Rosalinda isn't bad. It's an impressive name, just not really my style. I prefer either Roseline or some other variation, but I think I like pain and simple
Rose better than any of them.
The R names I like are
Rachel,
Raine (but mostly as a nickname for
Lorraine),
Riley (m), Rinoa, Roseline or
Rose, and
Ryder (m).
And I would go with Alexana, but what about Alexaña (alex-ahn-ya)? Very mystical and suiting for an elf doctor in my opinion.
