Did you hyphenate or keep your name when you got married (or what are you planning to do when you do get married)? Or for the guys, does it matter to you if your wife does not take your surname after you marry?
When we got married, I told Mrs. C that I didn’t care if she took my name, hyphenated, or kept her last name. She wanted to take my last name. When asked why she said always wanted a one syllable surname that was close to the top of the alphabet. (I knew I had a lot to offer to the ladies)
My guess is that confusion might arise when two married people with different names have children but given the number of divorces or single parent families I’m not sure if that would even be much of an issue any longer.
