Eileen Prince

Eileen Snape (née Prince) was a witch. She was married to Tobias Snape, a Muggle, and was mother to Severus Snape.

Early life
Eileen Prince was born into the Pure-blood Prince family. According to an old Daily Prophet clipping found by Hermione Granger, when Eileen was in her sixth year at Hogwarts School of Witchcraft and Wizardry, she was captain of the school Gobstones team. It is unknown exactly when Eileen began attending Hogwarts, but, based on the description of a copy of the sixth-year Potions textbook Advanced Potion-Making owned by her son as being "nearly fifty years old" in December 1996, it is possible that she started sometime in the early 1940s, if the book was bought new and then handed down. The House into which she was sorted is also unknown, although, given her son's desire to be sorted into Slytherin, it is possible she was one herself, or that Slytherin was the traditional house of the Prince family. Eileen may be like Andromeda Tonks (née Black), a pure-blood who married a Muggle-born due to a change in belief in blood purity.

Family
Eileen married Tobias Snape, a Muggle, and lived with him in a terraced house on Spinner's End. On 9 January, 1960, she gave birth to a son, Severus. Life in the Snape home was tumultuous, as Severus informed his friend, Lily Evans, that his parents were constantly arguing. Given that Eileen's son was described as not looking "well cared for" at age eleven, it is also possible that she and her husband were neglectful parents, abjectly poor, or both. Tobias does seem to have been aware of the fact that Eileen was a witch, having been described by their son as not liking anything, least of all magic. Eileen accompanied her eleven-year-old son to Platform Nine and Three-Quarters for the first time on September 1, 1971, an event later watched in a Pensieve by Harry Potter.

Physical description
At age fifteen, Eileen is described as having been skinny, pale, and sullen-faced, with a long face and heavy eyebrows. In 1971, as an adult woman, she was thin, sallow-faced, and sour-looking, greatly resembling her son.

Behind the scenes

 * Severus Snape took his nickname, the Half-Blood Prince, from his mother's maiden name combined with his own blood status of half-blood.
 * When Harry Potter accidentally entered Severus Snape's mind during an Occlumency lesson, he saw a memory in which a hook-nosed man was yelling at a frightened woman, while a small boy with dark hair — Severus — cried in the corner. The woman is generally presumed to have been Eileen, and the memory may be evidence that their relationship was abusive.
 * On his first train ride to Hogwarts, Eileen's son Severus shows almost immediate contempt for Gryffindor believing them to be brash and arrogant with no prior problems shown possibly inferring Eileen was bullied by Gryffindors while at Hogwarts passing the contempt to her son.
