Where do Archer and Fable come from?

Okay, this is driving Alex and me bonkers so please help! I was on StumbleUpon and I ran into this (and Girl Gone Child? Really? anyway…) and was like ‘Her kids are named Archer and Fable, how weird’ out loud and Alex said ‘Where have I heard those names before?’ and I said ‘There can’t be another mom out there who has named her kids that, can there?’ and so then he looked up baby names and, apparently, if there are siblings and one is named Archer, the other one is usually named Fable (and vice versa)...and so Alex set off in search of a story and though he found plenty of fables about random archers, he didn’t find any information on a song or a book or a thing containing Fable and Archers as characters…

So, the Google God has failed me…for once…now, I need you guys to help…if you’ve ever read anything where those two names came up, can you please please link me to it or tell me about it?...otherwise, I’ll just have to get over it and figure she’s just crazy.
