I'm always late on these threads--
I was married once, and had mostly changed back to my maiden name but still had a few things in the married name, then my dad died. Within a week I had everything back to my wonderful Irish name. Should I ever get married again - which I just don't see happening, but should it - I'll hyphenate my last name in honor of my dad. It's a wonderful last name, and it's all I have left of him....
I hyphenated my last name, not because I'm one of those kooky feminists, but because my dad had only girls and he's a splendid fellow and deserves to have his name carried on. The kids all carry his name too.
