I believe the model I've recently been calling Jenna Hale is actually Christy Hansen. I'd say the auction seller used this name and who knows where he got it (possibly from a magazine or...). Most of these guys are not so thorough as some of us here. So unless that name is found in a printed source from TLI I'll remove it from the index.
I also stumbled upon this pic from Debonair 1979-08. The text is good for a laugh but they do call her Christy.
