There is a rumor going around that JK Rowling is thinking of writing another book about Harry, Ron, and Hermione all grown up and they have children. But, that is just a rumor.
Harry's cousin's name is Dudley.
Harry Potter did not have any siblings, so he cannot have a nephew. He is, however, the godfather of Teddy Lupin, the son of one of his dad's best friends. Although J.K. Rowling has confirmed that Duddley Dursley, Harry's cousin, had non-magical children, they have not been named.
Antioch Peverell, CadmusPeverell and Ignotus Peverell. I believe Harry is a desiendent from Ignotus in paticular because it only mentions him having a son.
