James - an orphan?

Assuming that James is not the son of Voldemort, then I think it's safe to
say that his parents died before he did.  Otherwise, Harry would have moved
in with them instead of the Dursleys.  And even though you could argue that
Dumbledore left Harry with the Dursleys to hide him from the wizarding world
(which the Potters would have been a part of, since we have no evidence that
James was muggle-born), you'd think someone would have introduced Harry to
his grandparents by now.  It's mentioned that Aunt Petunia and Dudley are
Harry's only remaining blood relatives.

James was in his early twenties when he died (someone please refresh me on
why this is canon) so it is possible that his parents died after he moved
out of their house.  I tend to think that James' parents died after his
graduation from Hogwarts but before Harry was born - probably early victims
of Voldemort.
