The House of Blackwell was one of the oldest and most prominent pure-blood families in Britain. For a time, several hundred years before the inception of the Ministry of Magic, the Blackwell family ruled over the magical world of Great Britain. It was the first and last royal family of Wizarding Britain.

Family Origin

Details of the Blackwell family's origin are few

  • Blackwell is a British name, suggesting no foreign descent
  • The Blackwells were one of the oldest pureblood wizarding families in Britain
  • The Blackwells were already a highly regarded family prior to their ascension to the throne of Wizarding Britain. The means by which the Blackwells were given the title is unknown; though it can be assumed that either Camulus and Trinity Blackwell were the first to hold the titles of Duke and Dutchess of Wizarding Britain, or that Camulus inherited the title from his father -- this implies that Camulus Blackwell was the eldest son of his family.
  • The Blackwells held a very refined accent, suggesting that they were of noble or wealthy heritage.
  • The Blackwell family, while on the throne, resided in Blackwell Manor, located near Dover. This suggests that the family originates from this area. This may lead to the fine accent held by Blackwell family members.

Family Details

It is known that all members of the Blackwell family, dating further back than Camulus Blackwell, attended Hogwarts School of Witchcraft and Wizardry. Interestingly, unlike other pureblood families, the Blackwells were quite diverse in the houses into which its members were sorted. The following is a list of various family members, and which house they were sorted into:

  • Camulus Blackwell -- Gryffindor
  • Venatici Blackwell -- Slytherin
  • Kendaulus Moxus -- Ravenclaw
  • Augustus Blackwell -- Gryffindor
  • Antoinette Lafayette - Ravenclaw
  • Rodolphus Blackwell -- Slytherin
  • Paris L'Oreal Blackwell -- Ravenclaw
  • Horus Blackwell -- Hufflepuff
  • Medusa Blackwell -- Slytherin
  • Florence Blackwell -- Hufflepuff
  • Adolf Capricorn -- Gryffindor
  • Ji'Rah Blackwell -- Ravenclaw
  • Venezia Polaris -- Gryffindor
  • Khufu Blackwell -- Ravenclaw
  • Admiralia Blackwell -- Slytherin
  • Mercury Blackwell -- Hufflepuff
  • Constantine Blackwell -- Gryffindor
  • Maximilian Blackwell -- Ravenclaw
  • Sylvain Typhon -- Gryffindor
  • Insubre Blackwell -- Slytherin
  • Escaldes Blackwell -- Hufflepuff
  • Silure Blackwell -- Slytherin
  • Terrasse Blackwell -- Ravenclaw
  • Monoceros Blackwell -- Slytherin

The Duke and Dutchess of Wizarding Britain, when they were of the Blackwell line, took residence in Blackwell Manor, a lavish estate outside of Dover. The extended Blackwell family also lived in elegant estates, all of which were located in Dover as well. This led to Dover being the capital of magical activity in Great Britain from the 14th to the __th century, an possibly afterwards as well.

The Blackwell family was related to many of the other great wizarding families through marriage; Jean-Pierre DeTreville, husband of Alexandria DeTreville (nee Blackwell) was a very powerful wizard of the DeTreville family, a very famous French pureblood family. Likewise, the Blackwells were also related to a few non-magical or non-pureblood families; Victoria Windsor (nee Blackwell) married Percy Windsor, a very rich distant relation of the Royal Family of Great Britain, and thus relinquished her magical heritage -- even to the point of disowning her daughter Diana Capricorn (nee Windsor) after marrying into a wizarding family.

Family Tree

Funky Family Tree

The Blackwell Family Tree, starting with Camulus and Trinity Blackwell. See larger image for details.


Though the exhibited branch of the Blackwell family died out in 1800, it can be assumed that Camulus Blackwell, patriarch of the family, had brothers or sisters. Therefore, there was likely another branch or two of the Blackwell Family in existence at the same time; it is, however, unknown whether the other lines (if any existed) also died out.

But the Blackwell family would be remebered throughout the coming years as a highly respected and revered family.

And though no "Blackwells" lived on, descendants of the family existed under the name "Black" -- when Nakshatra Blackwell went insane, Monoceros Blackwell, her brother, attempted to distance himself from the family by changing his name to Monoceros Black, thus creating the Black bloodline. In keeping with Blackwell tradition, the Black family remained pureblood. However, a major difference between the two families were the attitudes of each. While the Blackwells were fair-minded and only mildly prejudice against muggles and half-blood/muggle-born wizards, the Black family took it to extremes. Monoceros Blackwell was one of the few intolerant and arrogant sons of the Blackwell family, and as such, when he created the Black family, he moulded it in his own image -- muggle-hating, pureblood-fanatical, Slytherin sorted.

The descendants of the Blackwell family would play an enormous role in the affairs of Voldemort, both to aid and hinder him. Many prominent Death Eaters (Bellatrix Lestrange, Narcissa Malfoy, Arcturus Black) were descendents of Monoceros Black. On the other hand, many prominent anti-Voldemort wizards and witches (Nymphadora Tonks, Sirius Black, Arthur Weasley) were also descendants of Monoceros Black.

After Monoceros Blackwell changed his name in order to distance himself from the shame his sister brought on the family, knowledge of the connection between the Black and Blackwell families still existed. Monoceros wife, whose name is unknown, knew of the connection; but for her, it was in fact a draw, because of the power and influence it implied. But after a few generation, when the Blackwell family had all died out, no one lived to remember the circumstances under which the Black family was created, and the connection was eventually lost to the ages.
