1. Happy Birthday!
Harry was born on July 31st, 1980. He was attacked by Voldemort in 1981 and he learned that he was a wizard 10 years later by a half-giant, half-wizard person. Sounds normal, right?
2. The Potter Family Tree
The Potters descended from their founding patriarch Linfred of Snichcombe and also from the Peverell family.
3. Names, Names, Names
Harry's grandparents were called Fleamont and Euphemia. Harry saw them in the Mirror of Erised during his first year at Hogwarts.
4. Everyone Is a Big Family!
Harry may be related to various other wizard families like the Blacks, the Malfoys, the Weasleys and the Longbottoms due to their long history. So Harry and Ginny could be related? Talk about awkward!
5. The Boys Who Lived?
Harry was born a couple of hours after Neville. Voldemort had two choices. The Potters or the Longbottoms. What if he had picked Neville? Would Neville save the world? Would he fight Voldemort?
6. Hide And Seek
Lily and James Potter were hidden by the Fidelius charm produced by Albus Dumbledore.
7. Are You Serious, Sirius?
Sirius pleaded for Hagrid to give Harry to him because he was the chosen guardian in the event Lily and James died, but Hagrid refused and followed Dumbledore's orders to take Harry to his aunt and uncle.
8. The Turban's History
Quirinus Quirrell claimed to have received his turban by an African prince in return for ridding him of a zombie. Sounds almost correct... Except the other way around, actually.
9. So Young...
Lily and James Potter died at the age of 21. They were only a short four years older than Harry when he fought Voldemort.
10. Malfoy's Fear
Lucius Malfoy's Boggart was Lord Voldemort, and Draco Malfoy's Boggart was Lucius Malfoy... Poor Malfoy!
11. Neville Is...
Neville is the godfather of Albus Severus Potter.
