I think it'll probably come back into popularity like so many other names have. Take my name for example. I'm 15, and when I was born my parents didn't know any other
Chloe's except my great great aunt whom I was named after, and now there are so many
Chloe's.
Pearl is a very lovely name. I would probably use it for a middle name, but that's just me. It'll definately make a come-back in popularity soon. But
Ethel, on the other hand...
