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. However, all the known female line's descendants of this family (the sons of Hesper Gamp and Sirius Black II and their descendants) were dead by 1996.

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).


Gamp is a colloquial, primarily British, term for an umbrella, believed to be derived from a character in Charles Dickens' Martin Chuzzlewit, nursemaid Sarah Gamp.

Notes and references

  1. This may be the case with Hesper Black née Gamp, as Horace Slughorn has claimed that all Blacks were Sorted into Slytherin. However, this may not included spouses, since members of other traditionally Non-Slytherin families were married into the family.
