Sorry, I suppose I was meaning that the fact it wasn't used in the US meant it looked like it suddenly became popular in the other places when perhaps it was just part of a trend along with
George which came back into fashion in the 90s. But I didn't explain myself very well! And really, I have no idea why it did become popular. I kind of link it to old names like
Ella,
Francesca,
Harriet,
Olivia etc which also became popular at the same sort of time. It kind of has a similar vibe in my opinion but that might just be me!
I can't think of any other cultural references at the moment which might explain it better.
