Eileen Snape (née Prince) was the mother of Severus Snape, one of the most beloved characters in the Harry Potter series. Eileen was a pure-blooded witch who married a Muggle man named Tobias Snape. This marriage was considered to be a bit of a scandal in the wizarding world, as Eileen was a pure-blood witch and Tobias was a Muggle.
Despite this, Eileen and Tobias had a loving marriage and raised their son, Severus, together. Eileen was said to be a very loving and devoted mother to Severus, and it is said that she was the original owner of the advanced Potions book that her son and Harry Potter would later come to own.
Though Eileen’s background is never explicitly stated in the books, there is evidence to suggest that she was indeed a pure-blood witch. For example, she was married to a Muggle, which would not have been possible if she was not a pure-blood witch. Additionally, her son Severus was a pure-blood wizard, which suggests that Eileen was also a pure-blood witch.
In conclusion, it appears that Eileen Snape (née Prince) was indeed a pure-blood witch. She was married to a Muggle, which would not have been possible if she was not a pure-blood witch, and her son Severus was a pure-blood wizard, which further suggests that Eileen was also a pure-blood witch. Additionally, it is said that she was the original owner of the advanced Potions book that her son and Harry Potter would later come to own.
