Hermione Granger's father

Mr. Granger is the father of Hermione Granger, a Gryffindor student in the same year as Harry Potter at Hogwarts. He is the grandfather of Rose and Hugo Weasley. Harry meets him in the summer before his second year when they go with Hermione to Diagon Alley to buy her school supplies. In 1997, Hermione modified his memory to think that he is daughter-less Wendell Wenkins. Hermione later finds her and restored his memory.
