Hesper Gamp

Hesper Black (née Gamp) was a pure-blood witch who married Sirius Black II. The couple had three children together: Arcturus, Lycoris, and Regulus.

She was a grandmother of Orion Black and Lucretia Black.

Etymology
Hesper is an English variation of the name Esther, which is believed to be derived from the Persian word for "star," possibly an allusion to the naming pattern of the family she married into.

The Book of Esther in the Old Testament tells the story of Queen Esther, the Jewish wife of the king of Persia who saved her people from extermination.

There was also one Esther by birth in the Black family – Hester Black.
