I think it makes more sense to keep the maiden name, especially since, with the professionals I'm around, there are issues of being in databases for publications and so on, where it can be a detriment to be listed under multiple names that don't get cross-indexed (but really, Pubmed needs a way to identify variants of a person's name -- it doesn't even handle the situation where a person is variably listed with and without their middle initial well. It ought to have some kind of unique ID for each individual author and allow attributions to be tagged back to it) /rant
I'd support anything my future wife wanted to do with respect to her own name. I do rather.want a child, and want a child with my last name...
I'm an only child, and it's the only chance my dad has.
