The Siblings M

I didn't put our last name in the title--guess I'm paranoid or something. We all started out as M's of course, and until about ten years ago, three of us remained with our last name beginning with an M. Sue went from a maiden M to a married M. Warren naturally has always been an M. I went from a maiden M to a married M and then remarried a P. Lynn, however, gave up her M right from the start, although she had one briefly after two H's. Now she's an O. I guess that makes her water because she's H2O. ha ha ha
