Your wife likes Emily doesn't she?? That is a perfectly lovely name, the only thing wrong with it at all, is that it's been at number one or in the top five for a few years. But now that SO many more names are used, it still means that a name at number one belongs to less than 1% of the babies born that year.
So, you go to the park and there are a hundred girls there born in 2008. Maybe one or two are called Emily.
Tbh I went all out of my way to pick an unusual name for my dc1 and now she wants nothing more than a cup of a pen with her name on it.
In 1975 or thereabouts, the number one name in America was Jennifer, and 5% of the girls born in that year bore that name.
Ella and Emma were your wife's other names weren't they?
What about Estella or Gabriella Suzanne. ?
Where's your wife? Is she really just sticking to her short list of three, not budging???? She's just waiting for you to give in!!
