In Narrative Telephone episode 6, Marisha named one of the members of the family as Eleanor Stassman, but it is unclear whether this is canon or not.
The Stassmans have had a taste for unique antiquities for decades. They have quite a collection and they pay well. The Gentleman sold the Stassmans the skull of Jourrael recovered from Molaesmyr. Two members of the family were killed when Obann and his group broke into their home to recover the skull.
