You're in a tiny minority, MUM! I'm not that keen on it myself, to be honest.
The associations with our erstwhile PM did it no favours for a long, long time, but it was already going out of fashion even in the 60s when I was born, especially in England. I'm Scottish and most of the women in my family in the generations above mine were Margaret, Elizabeth or Anne/Annie, with the odd Euphemia thrown in for good measure.
