Yeah, Frances is SUCH a family name for so many people, I'm sure it will get some use. I think Francine will come along as an undercurrent for people who would normally use Frances but have their eyes on the charts and want to be more chic lol. But the "Fran" syllable will be less abrasive and more uglycute to people, is what I meant.
I think -ine names will be back in a decade or two. We've had such an immersion in -ia names for so long that people are going to want to be less international and more specified IMO.
