I don't usually like -lee/-leigh names, either, but there are some that have an old-fashioned, down-home charm to them that I just can't resist. Novalee is adorable. It sounds very 1910s/1920s and quite quaint. Sidalee is another one that I kind of like, from the 'Ya-Ya' series.
It does sound made-up, but for some reason, and I can't put my finger on it, it seems to have more substance than something like Harleigh or Kaeleigh.
Novalee is charming. I've seen the movie and it is very heart-warming.
