Millie Winchester was the wife of Henry Winchester, a Man of Letters. She is the mother of John Winchester and thus is the paternal grandmother of Sam and Dean Winchester. It is unclear what her relationship with her son and her grandchildren is, as she is never mentioned by any of them. Millie herself ran a bed and breakfast in Maine, where she whittled wooden key holders for local children. Millie's current whereabouts are unknown; she was last seen in 1989. She still has a warrant out for her due to "an outstanding jay walking ticket" yet unpaid.
