I kept my last name when I got married. Hubby and I decided any boy children would have his last name, and any girls would have mine. We only have a daughter and she has my last name (my maiden name). Many Scandinavian countries do this only they slap a "-dottir" or "-son" on the end of the last name. It's never been an issue yet, except that my mom-in-law never gets my name right. I don't care if other people have a problem with it, it works for us.
