One could argue that you could justify an "Expert Skill: [power] Lore" skill for any Power origin that is relatively common in your campaign; and by "relatively common", I mean more people than just you possess it. Not necessarily PCs, but someone other than you has to have had it.

In the case of long histories regarding the Power origin, you could get some real use out of it.
