Well, I had never really researched this, but I'm from Quebec, and I know 3 Jolie. Maybe it's more prevalent there, or maybe I happen to know a coincidentally large number of them. If the latter, I guess that is a good learning experience for how your own life experience can easily bias you in your opinions and understanding of some things.
I was curious about this so I searched around a bit and found the data for girls names from 1980 to 2020 [1]. I've found 269 people with first name containing "Jolie". Then I took the census data [1], found that 45% of Quebec females are under 40. So extrapolating from the first number, I find 524 females with Jolie in their names in Quebec.
That means 1 in 7915 female in Quebec has Jolie in her name, compared to around 1 in 1 million for France. That explains (in part) how you know 3 and I don't know any I think.
Interesting, thanks for looking it up. I quite like the name personally, though it still seems I have some chance in my sample, since I do not know 7915 woman, so to know 3 Jolie still seems a little lucky.
