On her lifelong use of the name "Happy", in "The Happy Rhodes Interview" in Homeground #48 (Summer 1993) http://web.archive.org/web/20091023165015/http://geocities.com/SoHo/Studios/3450/homeground.html
Context: The first time my brothers saw me, when I was a day or two old and still in the hospital, my brother Mark could not pronounce the name "Kimberley," and I was an especially happy baby, so he decided it would be easier to call me "Happy." From that moment on, my family members never used the name Kimberley. I was forced, however, to use my given name while attending school. As soon as I turned sixteen, my name was legally changed to Happy Tyler Rhodes. As far as I'm concerned, it's the ony name I've ever had. When people ask me if it's my real name, I always say "yes."
