i do!! though i don't do very much with them since for the most part, ancestors or dancestors are like a "side story" to me, and don't effect much of the main story of my trolls if at all. i pretty much only have them for my teals too though LOL the miasmata is peridu's ancestor while my trio have dancestors that i messed around with a little (rorzak -> schade, pyrroh -> nietzi, valtra -> ??? noname yet). two of them even have toyhouse pages even though they're really underdeveloped right now!
