|Notable family members|
Gamp was the surname of a pure-blood wizarding family. They were related to the Black family, and more distantly to the Macmillan and Prewett families. It is unknown if this family is still extant or pure-blood.
Ulick Gamp was the first Minister for Magic, serving from 1707 to 1718, after previously acting as Head of the Wizengamot. During his term as Minister for Magic, Ulick established the Department of Magical Law Enforcement.
The only other known member of this family was Hesper Black née Gamp, who married Sirius Black II, the heir of the prejudiced Black family. She was the great-grandmother of Sirius and Regulus Black.
Behind the scenes
The Gamps were not part of the Sacred Twenty-Eight, indicating that, by the 1930s, they were either extinct in the male line or no longer pure-blood (as judged by the author of the Pure-Blood Directory).
