Warner, Sylvia Townsend, 1893-1978.
Lolly Willowes or, The Loving Huntsman (1925) - a middle-aged English
spinster accepts Satan in this amusing and engrossing work ... Highly recommended.

Movies
Many, many movies. But a few notable ones:
"Bell Book and Candle" (1958) Kim Novak & her family are
Manhattan witches. "Bewitched" the TV series took a lot of cues from this
story initially.
"The Witches of Eastwick" (1987) with an excellent cast (Susan
Sarandon, Michelle Pfeiffer, Cher, Veronica Cartwright, and Jack Nicholson
as, perhaps, the Devil).
"Buffy the Vampire Slayer" (1997-2003 TV series) -- numerous
witches, particularly Willow and Tara.
