I don't think it will be as dated as Ashley or Tiffany, simply because it was less common and for a shorter time :) I didn't know about the soap opera character but that kind of explain why its popularity was so short lived, maybe people forgot about it when the character disappeared.
Hahaha yes I think it would get misspelled a bit, but at least it is easier to say 'no, with a C' than 'no, K-A-Y-T-L-Y-N-N-E' ;) You have a really nice name! I love the flower :)
