don't get me wrong -- I agree it's probably just made up. I just thought it was interesting, and if the OP is trying to convince herself that the name has some connection to history in order to get along with her husband, she might use that as justification. ;-)
It actually does look a lot like that name Efriel, though, of which there are several instances of named females (older than 8) to be found by googling (not that that means it's a real name, nor that Ephreal comes from it, but it seems possible). I just wondered if you've ever seen that one before.
