Muggleborn

The term "muggleborn" was given to a witch or wizard who was born to a family of non-wizards; Muggles. By some wizards, these people should not be allowed to be trained to use magic, among them Salazar Slytherin, which is why it is very rare to find a muggleborn student in the House of Slytherin at Hogwarts.

Muggleborns do tend, however, to be some of the brightest students at wizarding schools. Both Lily Evans (later Potter) and Hermione Granger were muggleborns and both were the best students of their years, having top grades in all subjects.

Both Freedom and Mandy were wrongly called muggleborns by several students (and teachers), before it was revealed that Freedom's parents were Aslan and Cortina, both powerful magicians, and Mandy's parents had both been of the notable Race of Maiar, though both of them passed away before they ever had the chance to see their daughter.
