Ever since I was a little kid, I’ve been told that when I get married I shouldn’t change my last name. There’s only about 30 of us left with this last name and we want to keep the name alive. (My older sister’s last name is actually even rarer – there’s only 6 of them.)
Personally I’m not sure if I would want to change my last name some day if I do get married. It would depend on my future husband’s _{(wow that sounds so freaky)} last name and probably also the situation we were in. So I haven’t made up my mind completely yet.
But I don’t think women should automatically change their last names when they get married. It’s not a ‘must’ in my opinion.

My late stepfather actually took my mother’s last name when they got married.
