i have friends who are married and both are dr. hisname (they are medical doctors, though). it's pretty cute, actually, though i do not have full details as to why she chose his name, because obviously that isn't really appropriate to ask people randomly.

i can't imagine not having my last name. i feel so a part of my family and have only brothers, the married of which are fairly conventional, so we all still have the same last name. and i'm old, i've had this name a long time. but i would love to have a team name with my partner. i kind of do (we're in a band together, so sometime we go by myfirst bandname and hisfirst bandname). but i just don't think it'll work out. we won't have kids though so that's something we don't have to worry about.

i'm a big fan of combining last names into new names (as opposed to hyphenation) but this doesn't always work out very well.

that all said, i thought the entire point of going by ms. was to eliminate the married/unmarried signifier. do even if you take your partners name, it makes sense to continue going by ms. in situations where for whatever reason you need someone to know you are married to them, you would want to use their last name anyway, even if you weren't legally named that, because otherwise there'd be no point in going by mrs.
