Hector Dagworth-Granger founded the Most Extraordinary Society of Potioneers.
Behind the scenes
- In 1996, Horace Slughorn asked Hermione Granger if she was related to Dagworth - Granger during their first Potions lesson in her 6th year. She replied that she did not believe so, since she was Muggle-born. However, Hermione's closest magical ancestors were probably Squibs and would have lost all knowledge of magic from their family. Hence, Hermione could very well be related to him.
