Cecily was one of my favorite names as a teenager. I thought it was absolutely beautiful, with a very graceful look and sound. Now, however, I find it rather weak-sounding, too precious - and God forbid if the bearer has even a minor lisp! Any parents that would name their daughter Cecily (or Cicely, for that matter) would be well-moneyed and cultured, I feel like.
Your combo, Cecily Jane Elise, is beautiful. My stock combo way-back-when was Cecily Faye.
