It is perfectly fine to use this name.
Donna Elvira
&
Donna Anna
Donna in each case is used as a precursory title of gentry for "Lady" - as Princess Diana bore the title "Lady Diana" prior to obtaining her royal title. I learned these Characters from Mozart's Don Giovanni. "Don" is also the title of gentry for men.
