Glanfathans tribes are made of more than orlans there are wood elves and dwarves at least. http://pillarsofeternity.gamepedia.com/Glanfathan So you can role similar concept with other race. There are other backgrounds i think you can make work. Hunter, Drifter, Explorer, Mystic. I think you can fill in the rest of the back story with these cultures for instance drifter has on orphan track so you can fill in why you are an orphan ie colonists, war, disease, etc or hunter has a wilderness track, or explorer has a frontier track or mystic has a vision track. If you are not into the look of wood elves you can do a godlike wood elf so you get the size but not the look.
