Isla Black

Isla Hitchens (née Black) was a pure-blood witch and the sister of Sirius, Phineas Nigellus, and Elladora Black. She married a Muggle man named Bob Hitchens, and was struck off the Black Family tree and disowned as a result. Her dates are unknown, but she was born after Phineas (1847) and before Elladora (1850).

Behind the scenes

 * Based on a statement by Horace Slughorn, Isla may have been a member of the Slytherin House. However, she attended Hogwarts in the 1850s and 1860s, when Slughorn was not the Potions teacher.
 * Isla was the second earliest known disowned person in the family. The earliest known was Eduardus Limette Black.
 * In the movie Harry Potter and the Order of the Phoenix, Isla was shown on the Black Family Tree, but the name was not clear whether it was 'Isla' or 'Iola'. In the family tree which J. K. Rowling had drawn, the name was confirmed 'Isla'.

Etymology
Isla is the Spanish word for "island". It is also an archaic spelling of the Scottish island Islay, and the name of two rivers in Scotland. Her name probably refers to her isolation from the rest of the Black family.
