<Li> Cousin Mortimer: Mortimer (played by Dom DeLuise) was a witch and professional magician who appeared in Season Three's The Pom Pom Incident . When Valerie decided to try to become a cheerleader, Sabrina, fearing she may end up being as mean as Libby, sought Mortimer's help, and he gave her a coin that she had to just slip into Valerie's ear . It put Valerie off the idea, but not for long as she still expressed her wish to be a cheerleader, but, this time, Sabrina used her magic to convince Libby to give Valerie a second chance . Meanwhile, Mortimer put on a magic show for Harvey's little brother for his birthday, and, unfortunately, ended up sending him to Calcutta, India . Luckily, he managed to bring him back . At the end of his visit, Mortimer revealed he had hidden a clue to the family secret somewhere in the house . Sabrina found the clue under a cushion; a picture of a man in a Superman - type outfit with ABC on his chest (meaning "Spellman"). It was later suggested, by Aunt Hilda, that she and Mortimer were originally scheduled to sit next to each other at Sabrina's wedding, much to Hilda's dismay . Mortimer was never seen on - screen during this episode . </Li> <Li> Kong: Kong was the second to last relative to give Sabrina a clue to the family secret . Kong made a hand - only appearance at the end of Silent Movie . He had a blond woman (who was supposed to be Fay Wray) sitting on his palm . Hilda told Sabrina that Kong is a third cousin with a pituitary problem . Sabrina put the Fay Wray clue with a picture of herself and a picture of Robert E. Lee, and she then knew that the family secret was about the Spellman family . </Li> <Li> Edward "Ted" Spellman: Ted is Sabrina's father . He and Sabrina's mother divorced when Sabrina was ten years old, and he later gained a new girlfriend named Gail Kipling . Ted was played by Robby Benson when he appeared in the pilot episode and Meeting Dad's Girlfriend (Season 1 episodes), but was played by Doug Sheehan of Knots Landing fame in his later appearances (Season Four's No Place Like Home and the series finale where he arrives to walk Sabrina down the aisle). A few times in Meeting Dad's Girlfriend, Ted speaks in a loud, booming voice, possibly a reference to Disney's Beauty and the Beast in which Robby Benson provided the voice for Beast . </Li> <Li> Diana: Diana is Sabrina's mother . After the divorce, she became an archaeologist in Peru . Diana is mortal, and therefore has no magic . Also, she is unable to be with her daughter because of a term set by the Witch's Council; if they lay eyes on each other, Diana will turn into a ball of wax . Diana appeared four times in the series; she first appeared (briefly) in "Meeting Dad's Girlfriend" when Sabrina used the Sneak - a-Peek magnifying glass, but the identity of the actress playing her is unknown as it was an aerial shot, although some have speculated that it is Melissa Joan Hart's mother, Paula . In her second appearance (in Season Two's "Mom vs Magic"), Diana actually got to see her daughter after Sabrina was forced to choose between her mother and her magic after she sent her a letter (she later discovered that this was a test), and the two had a heart - to - heart when Sabrina was not sure whom to choose between Harvey and Dashell (she was played by Pam Blair). In her next appearance (in Season Six's "The Whole Ball of Wax"), Diana was turned into a ball of wax, and though Sabrina was able to bring her back, she was told by her aunts that if her mother turned into a ball of wax again, nothing would bring her back . Diana did manage to attend Sabrina's wedding in the series finale, but at a price as Zelda was temporarily turned into a candle (in her last two appearances, Diana was played by Alley Mills). </Li>
