Oooh right, So you like very classic female versions of male classics and she likes what's in the top ten!! sorry! I will find that tiny piece middle-ground where your tastes overlap! I hope.
I love Violet btw, What about Vivien? or Eve? JUST Eve not Evie!? All Softer than Violet I think. And what about Juliet? Like that, and it's more approachable than Violet (to an Emily/Ella-lover)
I like Rose, but it's become so popular it washes over me now without leaving any impression. I think Rosemary sounds more solid, less susceptible to fashion cycles iyswim. Rosemary could be crusty enough for you and cute enough for her if you use the nns, Rose Rosie or Romy.
Ella is a bit blah imo. Not quite enough of it though. JMO. I would like to know that an Ella had Annabella, Estella or Gabriella on her birth cert! I like to think you can adapt your name slightly to grow up alongside you. Or what about Eva instead of Ella? Sounds older I think. Eva was my Grandma's name.
Harriet is ugly. One of the worst mens' names adapted for women imo. Georgia is lovely one though. I don't dislike all female versions of male names.
Leading on to Charlotte. Charlotte is ok, but there are millions of them. I do love the nn Lottie though! That is so gorgeous.
If your wife likes Emily what about Jemima or Romilly? The have something of the feel of Emily in them I think!
Is it that you dislike her names, or that you think they're too popular, too ordinary??
Other suggestions that spring to mind; Elizabeth with Eliza or Beth for short, both pretty and Elizabeth could be Eli or Ella for short I suppose.
Susannah, very classic and old, nn Susie
Margaret - Maggie/Greta/Margot
I also like Marianne, it has a stuffy Jane Austen feel. But is still very pretty.
