Great-Grandmama Delilah Addams is a relative of The Addams Family.
She was played by Estelle Harris in Addams Family Reunion.
Delilah is Gomez and Fester's paternal grandmother and Grandmama's mother-in-law. She and her husband had the Walthzheimer's disease, which turned them into "pleasant" old people. She also wears a wig. She died while roller-blading with her headphones on and didn't hear a Mack truck coming. Grandpapa visits Delilah's marble crypt, which he keeps in his basement, every day.
