The Prewett family were pure bloods, Mr. Prewett (father of Molly Weasley) was a very well status man. He had three children. Gideon, Fabian and Molly Prewett. As we all know Molly married Arthur Weasley which disgraced herself and made her a blood traitor but kind at heart. Mr. Prewett also had a brother.
