What happened to Harry Potter's grandparents?

In the Harry Potter series, Harry had to live with his mother%26#039;s sister. However, Harry%26#039;s parents were 20 years old when they had Harry. Only a few years before that, they were in school at Hogwarts, and would go home to their families during the summer. So, what happened to James Potter%26#039;s parents and Lily Evans%26#039;s parents?

What happened to Harry Potter%26#039;s grandparents?
strange that they aren%26#039;t mentioned much in the book. but according to JKR they have little to do with the plot and died of natural causes (before or maybe just after Harry was born i assume).





James%26#039; parents were quite old and had him rather late in their lives but we don%26#039;t know anything at all about Lily%26#039;s parents.





but it doesn%26#039;t quite add up because James and Lily were 21 when they died (according to the dates on their graves in book 7). for both of them to have lost both their parents by that age.....very strange indeed...
Reply:She never mentioned them. But she does mention Harry ancestor uncle with the name Peverell.
Reply:Wow.... thats a really good question...........
Reply:I suspect that Valdemort got them while he was looking for the Potters. There%26#039;s also a possibility that Lily did what Hermione did and sent her Muggle parents into hiding. She might not have told Petunia where. Since she didn%26#039;t survive, they continued in their new lives with no knowledge of her or Petunia.





While you are at it, there%26#039;s no mention of how Mr. %26amp; Mrs. Black died either. We know how Regulus died, but his mother at least was still alive then. I suspect she demanded answers from Valdemort and was killed for it.





Valdemort was killing people right and left both times he rose to power. It really didn%26#039;t matter to him what their blood status was if they opposed him. He knew from his own lineage that a half-blood or a muggle born was likely to as powerful as a pure blood.

Reply:This is a good question. I think that she has ignored it.. But maybe she will answer in the encyclopedia or on Dateline OR in the live chat on Monday. Keep a watch out!





Oh, they%26#039;re all dead but not very important apparently. I think she sort of goose-stepped around that issue, when Neville lives with his grandma-- but there you go.
Reply:they probably died
Reply:Possibly James Potter%26#039;s parent died in battle against death eaters? Possibly Lily%26#039;s parents were already old when they had her and they died of old age, or heart disease, alcoholism etc.





They need to be dead for the purposes of the story, but their deaths are obviously not important for the story line or JK would have mentioned them.





You%26#039;re right, they are conspicuously absent though.
Reply:THey were probably killed because it does not mention them in any of the books
