This is a very personal choice.

I kept my maiden name for many reasons. Ironically, my second-line supervisor gave me a "talking to" about it (this was 1987 - husband and I worked in the same office at the time - because we eloped, everyone thought I was pregnant). In addition, my inlaws didn't "approve." My husband could care less, and if he had, he wouldn't have been the kind of man I'd marry.
