James Potter did not want to kill his son.
He killed both his Mum and Dad on Halloween.
James Potter also known as Prongs
Voldemort killed him to try to get to Harry..
Because harry potters dad, James, had a friend called Sirius and Sirius was a werewolf and to keep Sirius company whilst he was a werewolf he learned to be an animagus.
His mom and dad are dead in the book so he stays with his Aunt, Uncle and cousin.
Yes
Sand Man is about to kill him then his partner comes running and sand man kills Harry's dad by accident.
He had no brothers. NS James was a only child, he was born to his parents when they were rather old so they never had anymore children (or that's what I've read)
she loved john so much when her dad tried to kill him she told him,"If you kill him you have to kill me to." To tell your own dad you have to kill me if you want to kill this guy means a lot. If you don't understand this watch the Disney Pochohantas movie.

well he would love to get married and have kids someday
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.
