Jolie is as pretty as its literal meaning; nowadays it is also seen as a girls’ name, via Angelina for whom Jolie was originally her middle name.
Although it is French, Jolie is rarely if ever used as a name in France. In the US, it appeared briefly on the Top 1000 list in the seventies, then returned in 2000, following Ms. Jolie's 1999 Oscar win for Girl, Interrupted. It rose almost 100 places to reach Number 676 in 2016.
The name Joely, as in actresses Joely Richardson and Joely Fisher, is unrelated and pronounced differently. A nice association is the iconic Picasso painting, Ma Jolie.
