_____
There is no evidence Dumbledore killed Ariana. It could have been any of the three of them; Albus, Aberforth or Grindelwald. Dumbledore tells Harry that his greatest fear was that he struck the blow that ended her life, but Harry chooses not to ask whether he ever found out who was responsible for killing her, so we don't know. In fact, there is nothing any where that says Dumbledore killed anyone and considering his disdain for murder and the value he placed on intact souls (which are ripped apart when one kills), it is not likely he ever did.
Dumbledore's full name is Albus Percival Wulfric Brian Dumbledore, giving him three middle names.

You are very happy Love from Dumbledore
Dumbledore speculates that Merope put a very powerful love spell on Tom Riddle in order to make him fall in love with her.
I think it was Albus Dumbledore.
Gellert Grindelwald, the man he was in love with.
Yes. Albus Dumbledore had powers and wisdom Lord Voldemort could only dream of. However, Voldemort also knew things Dumbledore didn't or that Dumbledore would never use. Dumbledore's understanding of love alone makes him more powerful than Lord Voldemort as his failure to understand led to his downfall on multiple occasions.
According to the explanations given to him by Dumbledore, the power of love.
Albus Dumbledore's brother is Aberforth Dumbledore.
"Trouble at Hogwarts"
Dumbledore's full name is Albus Percival Wulfric Brian Dumbledore.
Dumbledore, obviously.
Grindelwald is the Dark Wizard that befriended Dumbledore in their youth, but who Dumbledore eventually defeated after he realized what he was. The Harry Potter author JK Rowling actually came out after the series was finished and declared that Dumbledore is gay and that he was in love with Grindelwald, who broke his heart (No Joke!).he was the villain before voldemort. Albus first was his friend, but when Albus realized Grindenwald was "evil", he turned against him and defeated G. in a duel.
No, Dumbledore is too old for her.
