Pure-blood or half-blood
Eileen Prince was a witch, the wife of Tobias Snape and the mother of Professor Severus Snape. She attended Hogwarts School of Witchcraft and Wizardry in her youth, and owned a copy of Advanced Potion Making, which she later passed on to her son.
However, the marriage went sour, with Tobias shouting one day at Eileen as she cowered in fear, while their son wept in a quiet corner; this seemingly was a frequent occurence.
When her son went to Hogwarts for his first year, Eileen accompanied him to Platform Nine and Three Quarters, looking grave and serious the way her son would go on to appear in adulthood.
