What do you think of this middle name?

I work with a woman who's last name is May, and although May is generally accepted as a feminine name, if it's a family name I think it's fine. People generally do not use their middle names on a regular basis and for the most part he'd be Oscar M. XXX and most people would never bother to ask what the M is for. If it really means something special to you it's worth it to try to convince hubby to go with it. Good luck!
