Lydia Spellman is a witch and the grandmother of Sabrina Spellman. Lydia has five children: Edward, Hilda, Zelda, Vesta, and Sophia Spellman.
Lydia is very controlling and often gives her children back-handed comments. Hilda and Zelda have a lot of issues with her that usually come to light in flashbacks and stories throughout the series.It is revealed that when they were little, Vesta turned her mother and father into pigs because she was insanely jealous of the attention they gave to Hilda and Zelda. Because the Witches Council decreed that people with pig's feet couldn't properly raise children, Hilda and Zelda were adopted by a nice family on a farm. After Lydia head butted Vesta, she turned them back into people.
