I like them all really! I think Vivienne is old enough for a come-back, Evelyn is still in style enough, especially with the popularity of Eve. Eleanor is my personal favourite from the list, I just love grand-ma names when they're ready to make a comeback! lol
Louisa is the one I'm not loving quite as much. Louise for me is still a bit young for a comeback, but way too old for a kid and Louisa is "cooler" than Louise by a lot, but still, for me, not "there" yet. "Lou" has that baby boomer vibe, it's a generation away from coming back lol
