It's pretty. My first attempt would be to say it like Rose-Elaine. It could be anything though.
Even Rahz-uh-lie-nuh.
Elaine is more appealing on paper than
Ellen, however I think I'd rather meet an
Ellen IRL.
My favorite invented
Rose names are Rosemarina / Rosemarine, Roseamy (Rose-Amy ... it's better hyphenated), and Roseve.
