Beautiful name.
I get the impression some people think it's a modern made-up name. It isn't. I found three women named Rosabel in my family tree, the one furthest back being born in the late 18th century.
People suggesting Isabel as an alternative, but how is Rosabel 'bad' and Isabel okay, both are genuine names?! I much before Rosabel, as Isabel/le (and Isabella) are overdone.
