Eileen Snape (née Prince) (born c. 1929) was a British witch, wife to the Muggle Tobias Snape and mother to Severus Snape.[7]


Early life

Eileen was born into the wizarding Prince family[7] in Great Britain, likely around 1929.[1]

She likely began attending Hogwarts School of Witchcraft and Wizardry around 1940.[1] Presumably, she was Sorted into Slytherin.[6] According to an old Daily Prophet clipping found by Hermione Granger, Eileen was Captain of the school Gobstones team during her fifth year.[3] She was concurrently the President of the Hogwarts Gobstone Club.[4]


After graduating, Eileen met the Muggle Tobias Snape and married him.[7] Why they began a relationship and got married is unknown. Their son would later state that Tobias did not like "anything much", including magic. It is possible that he was unaware of the magical world and Eileen being a witch, or else he might have ended the relationship. They moved into a terraced house in Cokeworth on a street called Spinner's End. It was close to the mill and near a nasty-smelling, polluted river.[8]

Eileen's decision to marry Tobias may have resulted in her being disowned by her family — similar to Andromeda Tonks, who was disowned by her family after she married a Muggle-born man.

On 9 January, 1960, she gave birth to a baby boy, Severus Snape.[7] Severus' childhood was plagued by the tumultuous, explosive atmosphere in the home, with his parents often fighting.[5] Tobias would shout at Eileen and may have been physically abusive as well.

The couple either neglected Severus, were too poor to care for him well, or both. His clothes were mismatched and did not fit properly. When he began his first year of school at Hogwarts, he changed into his uniform quickly after getting onto the Hogwarts Express, apparently glad to be rid of his Muggle clothes.

Despite this, Severus was already talented with magic before he even received his Hogwarts letter in 1971. In 1995, Sirius Black would mention (in a conversation with Harry Potter, Ronald Weasley, and Hermione Granger) that Severus knew more curses when he arrived at school than many of the seventh-year students did. Tobias might not have tried to ban magic from the Snape home, or Eileen and Severus might have used it whenever he was not around.

On 1 September, 1971, Eileen accompanied Severus to Platform Nine-and-Three-Quarters at King's Cross Station and watched him leave on the Hogwarts Express.[8] Although she looked sullen, it can be presumed that she was happy to see her son get away from their troubled home for a while (except for the summers between his school years). He looked exceptionally overjoyed.[8]

Later life

What precisely happened to Eileen is unknown. By the time Severus joined the Order of the Phoenix and began teaching at Hogwarts in September 1981, he had taken over the home.[9] As he was only twenty-one years old, Eileen and Tobias were probably alive but had moved away for some reason.

Physical appearance

At age fifteen, Eileen was skinny and unattractive, looking simultaneously cross and sullen. She had heavy brows and a long, pallid face.[3] By 1971, not much had changed: Eileen was thin, hunched, sour-faced and sallow.[8]


"Eileen" is from Celtic, English and Irish roots and has a long-standing history in each culture. In Irish, it is known as a variation of "Helen". It became a more popular name in the 19th century. It is rumoured to have roots in Latin, American, French and Greek cultures, however, such claims are not backed up with much evidence. Another variation of this name is Eileene which is most commonly used in Ireland.

Other versions of Eileen; "Aileen" (Scottish), "Eibhlin" (the original source for the name), "Eila" (Celtic variant of both "Eileen" and "Aileen"), "Eireen" (Norwegian variant of "Irene" or "Eileen"), "Eleanor" (a similarly-rooted name to "Eileen" in Irish).

Eileen's maiden name was PrincePrince is a general term for a monarch or a member of a monarch's family, and is a hereditary title of some European royalty, likely alluding to the aristocratic status of pure-blood families in the wizarding world. The word is derived from the Latin princeps, meaning "a prime", which was one of the titles of the Roman Emperor, in which case it was generally translated as "First Citizen". The Prince is also the title of a famous political treatise by Niccolò Machiavelli; an interesting point considering that the adjective derived from the author's surname, Machiavellian, is defined as "attempting to achieve goals by cunning, scheming and unscrupulous methods", which may allude to the ideal traits of Slytherin house.[10]

Behind the scenes

  • At Hogwarts, her son Severus used her surname and his blood status to make his nickname of "the Half-Blood Prince".
  • There is a theory that Irma Pince, the librarian during Harry Potter's years at Hogwarts, is actually Eileen in disguise. Pince's name is an anagram of "I am Prince" or "I'm a Prince". Her description matches that of Eileen's, having the same hooked nose and dark hair as Severus. Both she and Severus have snappy, stern personalities. She is a librarian and, incidentally, the sitting room in the Snape home contains many shelves of books (as seen by Narcissa Malfoy and Bellatrix Lestrange during a visit in 1996). Eileen was willing to marry a non-magical man, Tobias, and Pince was rumoured to be involved with Argus Filch, the Squib caretaker of Hogwarts.


Notes and references

  1. 1.0 1.1 1.2 As Eileen's sixth-year Potions book was published "around" 50 years prior to 1996 (Harry Potter and the Half-Blood Prince, Chapter 16 (A Very Frosty Christmas) ), it would have been published around 1946; assuming Eileen bought it new, and she being sixteen at the time, she would have been born around 1929, although she may have alternatively bought a used copy or purchased it earlier.

Additional supporting evidence is that Severus wanted to be in Slytherin before he even got to school, potentially from hearing about his mother being in Slytherin.
