Eileen and Tobias.
Severus Snape's mum was called Elieen Prince. She was a pure-blood witch who married and had a son with muggle Tobias Snape.
His mother was Eileen Prince, pure witch, and father was Tobias Snape, muggle.
It is unknown whether or not he did, but if he did, it is likely that it was Tobias, after his father.
No, Snape is the half blood prince. His mother's name was Eileen Prince, who was a witch, and his father, Tobias Snape, was a Muggle. In Harry Potter and the Half Blood Prince, Snape admits this to Harry.
He was born to a pure blood witch-Eileen Prince and a muggle called Tobias Snape.
"Half-Blood Prince" is a nickname Snape made up for himself when he was a student at Hogwarts. Snape's mother was a pure-blood witch named Eileen Prince while his father was a Muggle named Tobias Snape. Thus, Snape is literally the half-blood member of the Prince family. The Half-Blood Prince's book is Snape's Potions textbook from back when he was a student at Hogwarts.
