Aberforth Dumbledore

Aberforth Dumbledore is the Numenorian son of Kendra, and Percival Dumbledore, and has become the somewhat leader of Hogsmeade, and a powerful member of Hogwarts. Aberforth has two siblings in the form of Albus, and Ariana of which his brother Albus is the leader of Hogwarts and someone he is very bitter with over the death of their sister, and his sister Ariana was murdered by the dark Magi Grindewald and he blames himself for her death but she remains with him in the form of a living painting.

The Dumbledore family was traumatised when Ariana, then six years old, was attacked by three Muggle boys who had seen her performing magic. The attack left Ariana half-insane and unable to control her magic. Their father cursed the boys in retaliation, and was arrested for it. He did not reveal to the authorities the reason for his attack, as Ariana would have been taken from the family as a threat to the Statute of Secrecy and placed in St. Mungo's Hospital for Magical Maladies and Injuries permanently. Percival was imprisoned in Azkaban, and Kendra moved the family to Godric's Hollow, putting out a story that Ariana was ill and needed to remain at home. This story led to the assumption that Ariana was a Squib.
