Hm, I'm not sure exactly what Renaissance style is, but like
Lissa I can throw out suggestions for you to consider:
Girl:
Sabrina,
Serena (if she's a bubbly personality, this name could occasion remarks on how inapt it is!),
Cherilyn,
Delia, Tacie (not
Tracy), or Bekah. I like
Lissa's suggestions of
Tabitha and Devonny.
Boy:
Thad,
Neil,
Ty (
Titus,
Tyler,
Matthias),
Rhys, or
Ian.
Jaxon and
Jareth (also
Gareth) are good Novel Names as well.
Hope this helps.
