Slytherin family

The **Slytherin family** was a pure-blood family with several notable members, particularly Salazar Slytherin, one of the four original founders of Hogwarts School of Witchcraft and Wizardry, who lived over one-thousand years ago and is the earliest known member of Slytherin house.

Not much is known about this family, but it is possible that they, like their relations, the Gaunts, and several other pure-blood families, had a tendency of marrying their cousins to keep their blood pure and to retain the traits of their ancestors (most notably, the ability to speak Parseltongue). Many dark witches and wizards came from this family, including Salazar Slytherin himself, Voldemort, the last descendant.

## History

### Early history

The Slytherin family was a prominent one in the wizarding world, as demonstrated by their famous ancestor, although over time their gene pool became unstable due to a habit of inbreeding. They slowly squandered their wealth, which was completely non-existent by the time their last descendants, the House of Gaunt, came to be.

### Recent history

By the early twentieth century, when the family was extinct in the male line, Marvolo Gaunt, their last known descendant from the female line, had only two children, Merope and her brother Morfin. While Morfin regularly used magic to terrorise Muggles and spoke almost exclusively in Parseltongue, his sister exhibited no dark qualities and was in fact so traumatised by emotional abuse inflicted upon her by her father and brother, that she was barely able to use magic and often presumed to be a squib.

Merope later ended the pure-blood line of her family by marrying a Muggle from a nearby town, Little Hangleton, and having a half-blood son, Tom Riddle, who later became the infamous Dark Wizard, Voldemort. The female line of the Slytherin family continued for several years, seemingly ending with the death of Riddle.

## Members

### Salazar Slytherin

Professor Salazar Slytherin was a great wizard of Medieval times. He was a Parselmouth (a wizard with the rare ability to speak with snakes), and skilled at Legilimency. Salazar was one of the four founders of Hogwarts School of Witchcraft and Wizardry. As he didn't trust Muggle-born students, he expressed his opinion against accepting them at Hogwarts. However, when the other founders didn't agree, Slytherin left the school and did not return. It is unknown when he died. Salazar Slytherin's portrait still remains at Hogwarts.

## Descendants

### Isolt Sayre

Professor Isolt Sayre (1603 – 1703) was a talented Irish witch and a direct descendant of two skilled ancestors, Salazar Slytherin and famous Irish Animagus Morrigan. She was a skilled healer, herbologist, potioneer, and especially proficient at concealment and protection charms.

She along with her Muggle husband James Steward and adoptive sons Chadwick and Webster Boot founded Ilvermorny School of Witchcraft and Wizardry the first school of its type in North America. Isolt and her family are credited with the downfall and death of her aunt the Dark Witch Gormlaith Gaunt. She died over the age of a 100 in her beloved Ilvermorny where she and her husband laid to rest. Isolt and James' statues still stands today flanking the front doors of Ilvermorny castle. Her twin daughters Martha and Rionach Steward (Martha being a Squib and Rionach being a supposed Parselmouth) were the last of the Gaunt family's American branch both having no descendants.

### Tom Riddle

Tom Riddle (31 December 1926 – 2 May 1998), later known as Voldemort, was the most powerful Dark Wizard in the history of the wizarding world.

Tom was born to Merope Gaunt, a pure-blood witch descended from Salazar Slytherin who died shortly after childbirth and Tom Riddle Snr, a wealthy Muggle who was only with Merope due to a love potion and left her when it ran out. Riddle died by the conclusion of the Battle of Hogwarts at age 71.

### Other families

The Slytherin family, like many of the pure-blood families, had some relation to many other families in the wizarding world. The Peverells, Gaunts, Blacks, Malfoys, Potters, Weasleys, Prewetts, and other families are all linked to one another through bloodlines and intermarriage.

The only known direct descendants from Salazar Slytherin were the Gaunts, who for the most part shared their ancestor's beliefs in the purity of wizard blood. They also spoke in Parseltongue between themselves. Tom Marvolo Riddle and his daughter, Delphini, were the last known descendants of the Gaunt family and spoke Parseltongue as well.

The Gaunt family was also descended from the Peverells, although it is unknown if one of the two infamous bloodlines preceded the other or if they simply merged at some prior point.

## Heirlooms

The family held onto Salazar Slytherin's possessions for many generations such as his Basilisk horn wand and his locket and in later years Marvolo Gaunt was in possession of a signet ring passed on from his Peverell ancestors. However, the locket left the family when Merope sold it to Borgin and Burkes in order to support herself while she was pregnant. It later came into the possession of Hepzibah Smith, whom a teenage Tom Marvolo Riddle killed and stole the locket from. Riddle eventually turned both artefacts into horcruxes; the locket was stolen from its hiding place by Regulus Black and later destroyed by Ron Weasley, while the ring was destroyed by Albus Dumbledore with Godric Gryffindor's Sword. The ring also contained the Resurrection Stone.

## Etymology

*Slytherin* may refer to the words "sly" as well as "slithering", which is the form of locomotion of snakes, possibly referring to their rare ability to talk to snakes called parseltongue.
