Lucretia Black

Lucretia Prewett (née Black) (1925 – 1992) was a pure-blood witch, the eldest daughter of Arcturus Black III and Melania Macmillan and sister of Orion. She married Ignatius Prewett, making her an aunt by marriage of Fabian, Gideon and Molly Prewett (later Weasley). She was an aunt by blood of Sirius and Regulus Black through her younger brother.

Etymology
Lucretia was a legendary Roman maiden who was raped by the son of the king of Rome, an event which triggered the toppling of the monarchy and the establishment of the Roman Republic. She commited suicide in public protest against dishonor. The name is from the Roman family name Lucretius, possibly derived from the Latin lucrum, "profit, wealth." Also, Lucrezia Borgia was a Renaissance noblewoman from a family notorious for its ruthlessness and corruption.

Behind the scenes

 * Based on a statement by Horace Slughorn, Lucretia may well have been a member of the Slytherin House. However, she attended Hogwarts c. 1936 - 1943, when Slughorn may not have been Potions master.
 * Since Lucretia and Walburga Black were born on the same year, it is most likely that they were classmates at Hogwarts.
 * Lucretia is depicted on the family tree tapestry very much like Misapinoa Blishwick (née Black). While Lucretia is depicted with a sad face, Mrs Blishwick is depicted with a smile.
 * 281 Lucretia is an asteroid belonging to the Flora family in the Main Belt. It was discovered by Johann Palisa on October 31, 1888 in Vienna. It is named for the middle name of Caroline Herschel, one of the first female astronomers.

Appearances

 * Harry Potter and the Order of the Phoenix (film)
