I have a Lauren and it seems to be pretty unique at every school she has attended. That said it wouldn't have been my first choice... Or second... Or third.
Very weirdly Jessie and Natalie were on my list so I'd choose Jessica out of the three, although where I lice there are four or five Jess, Jessie, Jessicas in my daughters year.
I will say of all my children Lauren is the only one who seems to really like her name, although someone once called her Loz which I stopped immediately 😂
