Hi! I've met someone named this after their great-great grand father. They're female, so it's written with two Ls instead of one. It's pronounced AY-lee but a lot of people just call her Ellie, because it's more common and easier to pronounce. If you meet someone with this name, try to remember the accent, it's often forgotten and will probably be much appreciated.
