Erin Chambers

Erin Chambers is Rita Barksdale's daughter, who appears to have been raised to be a trophy wife. Based on information in the episode "I Don't," it appears she was 21 years old when she got married. She is the only cousin of Daria and Quinn Morgendorffer on their mother's side of the family. Daria has a low opinion of Erin.

In "Aunt Nauseum," it is revealed that Erin married Brian Chambers because he gave her herpes and she thought no one else would want her. In this episode, Erin wants a divorce but is eventually talked out of it by Brian and her grandmother, leading to a second honeymoon for the two.
