I skipped on some of this thread, too, so hopefully it's not redundant...

I am one of the children with both my mom/dad's names. My mom kept her name when she got married, I've heard that it was because 1) she had already started a professional career and didn't want to confuse anyone, and 2) she doesn't like that taking his name is following the old convention of the husband owning his wife. I was born Aubrey Dad'sLastname, and got the option in first grade to add my mom's name on, so now I'm Mom'sLastname-Dad'sLastname. A LOT of people think that I'm married because I'm hyphenated, but I'm not. But I like having my name hyphenated because it makes it a completely unique name, and I'm pretty sure that even though I have a LONG signature I am not ever going to take my future DH's name, if ever there be. My sister took her husband's name when she got married, and now I think her name sounds silly instead of unique. And now I'm really the only person in the world with my name. That's really cool . I bet though that when/if I have children, they'll have my theoretical DH's name, to make things simple....not sure though.
