Madonna

This name was also used among the English Romani community in the 1800s:

Catholics don't name their children Madonna; that would be blasphemous. I live in Ireland and nobody here would be called Madonna. I find it strange that there are more comments that this name shouldn't be used because of the singer rather than because "Madonna" is a title reserved for Mary alone.

Whomever stated that Roman Catholics don't name their children Madonna is misguided: this is my aunt's name, and she as well as my grandparents were/are practicing Catholics.
