I agree with Ducky. I reckon she was a maiden who was experimented on by Seath in his desperate search for immortaility. The experiment went wrong and she was cast out of Anor Londo ( likely imprisoned in the Undead Asylum as the doll is found there). My opinion is that the Painted World was created by Ariamis to contain these failed experiments ( the crow demons and engorged zombies are also failed creations) and the lonely Priscilla was drawn into the realm.
