When we got married in 1972, I did not take my husband's surname. (There were two Mrs B...s at the time, my MIL and my FIL's second wife). It was far less common then. I use Ms, not Mrs. I have one family member who insists upon sending me cards address to Mrs Mary B...., even though it's not my name. It really annoys me. It's as if she thinks it's the law that you have to change surnames on marriage. And no, it's not in the least confusing. My two married daughters have both taken their husbands' surnames, which disgusts my feminist oldest daughter. It means all five of us have different surnames as oldest "turned her name inside out", preferring my mother's surname, which she had been given as a third forename. I am interested in all this, as you can tell! I wrote a book about names (now o.p.), published in 1983.
