I've met a few Marys under 40, but not many... I can think of 4 Marys, a
Maryanne and a
Mariana.
as for
Jennifer.. yes some of us are sick of it, but w/ it being so overused in the 70s, it's possible there are namesakes for friends and aunts... though I'd look at the person's mn instead
Rachel's still listed in the top 30 in BC
as for
Caitlyn, I prefer the spelling
Katelyn to either of those spellings...
