I don't imagine Luna was used much as even a girls' name back then. It doesn't fly, not just because of precedent but also because Luna and all things moon are strongly associated with women/goddesses/menstruation, etc.
Luna is a common Spanish surname.
Also there is a place in Germany called Merseburg-Leuna.
