I too have been in seach for a meaning. My mother died when I was young so i couldn't ask. I did a paper on it when I was younger a remembered finding the word "Dare" in the Oxford Englisg Dictionary. At some point there was a referenec to a old english derivitive of the name "Dareth" refering to a girl who was bold or fearless. It seems to suit me. The irony here is that you and I are similar in age. I was born in 1979. Our mothers most have scene something similar but I don't think mine would have gotten it from a television show but who knows. What game show was it and do you know her full name?
I don't think I will come back here so please email me
