Did Harry Potter have grandparents

Answer 1

Yes, he had two. His father's father, a pure-blood wizard, and his mother's father, a muggle.

Neither of them were named or seen during the series and both were dead before October 1981.

Answer 2

Yes, but we never know if he met them or if they were alive during his life because it is never mentioned in the book.

However in the first book, Harry notices that in the mirror of Erised ( which is "Desire spelled backwards, by the way) an old man is there that seems to have Harry's knobbly knees. This could possibly be his grandfather.

Answer 3

Actually Harry Potter Has no Siblings. But his grandparents are not mentioned in the series. He actually sees his Parents in the Mirror of Erised. (Lily and James Potter)

Answer 4

None that are alive. His mothers parents were both muggles and his fathers parents were a witch and wizard.

Answer 5

Yes, he was brought up by his Aunt Petunia (his mother's sister) and Uncle Vernon.
