Who is Mother from Wanda Hickey's Night of Golden Memories and what is their importance?

The Grandstand Passion Play of Delbert and the Bumpus Hounds shows Mother to be a bit of a quiet woman who merely accepts life as it comes her way. She may have had plans and ideas in the past, but her life now is one of endless meals of meatloaf, mashed potatoes, red cabbage, and coffee grounds. Her reaction to the Bumpus clan next door is one of shock and eventual acceptance, not having enough inside of her to actually fight against the situation. She takes very good care of her family, and spends countless hours preparing the Easter Ham because it is the tradition of the family. How her heart must have broken when the Bumpus hounds devoured their lovely dinner.
