Helen Chambers is Diane Chambers's mother. She is first mentioned by Rebecca Prout in Any Friend of Diane, but doesn't appear until Someone Single, Someone Blue. Because of her previous marriage, Helen is extremely wealthy, though she claimed to have lived in poverty before she met Diane's father. He loses almost all of the family wealth due to Sam & Diane's failed marriage. However, she ends up forming a relationship with the family servant Boggs, who confesses that he made a living off of embezzling from the Chambers family for a quarter of a century.
