Irma Crabbe

Irma Black (née Crabbe) (b. 4th June 1908) is an English Pure-Blood witch and a member of the Noble and Most Ancient House of Black through her marriage to Pollux Black, an arranged union brought about by their parents when Irma fell pregnant with their first child Walburga. Two sons, Alphard and Cygnus III, would follow and through them Irma is the grandmother of Sirius Black III, Regulus Black II, Bellatrix Lestrange, Andromeda Tonks and Narcissa Malfoy, as well as the great-grandmother of Nymphadora Tonks and Draco Malfoy. A notoriously bad-tempered woman, Irma and Pollux utterly despise each other and she is both feared and avoided by her descendants.
