Grandma Barksdale

Helen Morgendorffer's mother, who is never directly seen or heard from in the Daria series. Her presence, however, is felt from Erin's wedding onward ("I Don't"). It is implied that she is unable to travel, and also implied that she is well off enough financially to afford showering Rita and her daughter Erin with gifts and windfalls. Of her three daughters, she is closest to Rita Barksdale and appears to favor her over Helen and Amy. This spawned a long-running feud between the three sisters that is finally (one hopes) resolved in "Aunt Nauseam." Before then, Helen occasionally rants about the unfair treatment Rita gets, said rants being remarkably similar to her husband Jake Morgendorffer's rants against his father.

Fanfiction
The character was expanded in numerous fanfics. Kara Wild named her Evelyn in the Driven Wild Universe and made her generally crusty, but loving. Later, Richard Lobinske would create Tess Barksdale, the southern matriarch in the fanfiction series, Falling Into College.
