Yeah, every woman I have ever met, changed her name to her husband's on marriage. I see dozens of women on here, claiming they kept their surname, and every women they know did. But I don't know one in real life. Genuinely.
And I know people from all walks of life. From working class non-professionals who are not massively educated and have just school qualifications, to highly educated middle class professionals. (And some upper class folk too.)
From vicars, doctors, consultants, dentists, bankers, CEOs, police, and rich land owners with very large houses/mansions, to shelf stackers, nannies, hairdressers, receptionists, actors, and musicians. Women from all walks of life. And many age groups. ALL took their husband's name when they got married.
Despite the many posts from some posters on threads like this, IME very, very few women keep their old surname when they get married. Even the most ardent feminists take their husband's surname.
