Hi Bob,

>Is that common in Germany?

Legally, there's no preference. In reality, though, it's mostly the women that take the man's name. Followed by couples that hyphenate both names. However, the number of men taking their wife's names is slightly increasing. The same is true of couples that keep their names as Andy and Marcia did.

>Who's last name did you take?

My wife's last name.
