Sobriety Ogg
A former husband of the matrilinear Nanny Ogg, whom she has outlived by at least thirty years. Accepted (at least in public) to be the father of Shawn Ogg, and nobody stops to consider the inconvenient fact that Sobriety died a good ten years before Shawn's birth... then again, if a witch was doing the telling, then it must be right... only ignorant outsiders would raise this point, and are generaly shushed up.
