Aurelius was an illegitimate child of Aberforth's. His mother is killed, and as a result Aberforth is unable to care for his son. Credence is taken to America and put up for adoption, a fact known to no one but Leta Lestrange (Zoe Kravitz).
Aberforth's son is Aurelius Dumbledore, born after he fell in love with a girl in Godric's Hollow. However, the girl was sent away, either before or after Aurelius's birth. His son was adopted by Mary Lou Barebone and renamed Credence Barebone.
Fantastic Beasts 3 reveals that Credence is Aberforth Dumbledore's illegitimate son. Since Grindelwald was telling Credence the truth about his name being Aurelius Dumbledore, it seemed logical that he's one of Albus Dumbledore's siblings.
Harry recognizes the man's blue eyes as those he's been seeing through the magic mirror, and he realizes that this man must be Aberforth, Dumbledore's brother, and that Aberforth was the one who sent Dobby.
By this point, Credence was slowly dying as his Obscurial nature poisoned him, the real reason that his phoenix had come to him, something that Dumbledore had recognised after having seen something similar with his sister Ariana, who was also an Obscurial.

Is Credence actually Snape?
Fantastic Beasts: The Secrets of Dumbledore confirmed that Credence Barebone/Aurelius Dumbledore (Ezra Miller) is the new Snape (Alan Rickman) through a very familiar line delivered by Aberforth Dumbledore (Richard Coyle). Fantastic Beasts 3 finally shed light on the Credence being Aurelius Dumbledore plot twist.
Honestly, Hermione knew Dobby was a lost case... nothing could have revived Dobby after the attack or she would have definitely helped Harry with Dobby considering she was the girl who started S.P.E.W(Society for the Elfish welfare) and fought for elf rights. There was nothing to be done at that point.
Harry asked for help while looking at a two-way mirror; Aberforth had the other mirror. He sent Dobby to rescue them; the house-elf did so, stating that "he would always be there for Harry Potter", but was killed by Bellatrix Lestrange.
Really though voldemort would have killed him easily, as could many of the death eaters I suspect. He isn't is brother and never had any interest in being like him it seems. Aberforth himself seems to know it, having given up the fight by the time Harry meets him.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
Although Aberforth was a brother of Albus, he did not study the art of magic as much as Albus did. He cared more for the Dumbledore family than Albus did and abandoned his studies to help them out. He was powerful, but not quite as powerful as Albus.
His mother is killed, and as a result Aberforth is unable to care for his son. Credence is taken to America and put up for adoption, a fact known to no one but Leta Lestrange (Zoe Kravitz).
As he had previously believed Credence could have been saved had he been given enough love, this indicated that at its earliest stages, it would have been possible for the power of love to cure them of their obscurus, but at a certain stage, a wizard/witch with an obscurus will no longer be able to be saved.
Since Harry was looking at the mirror shard before Snape's Patronus appeared, and the inside of the Hog's Head was seen, the most likely explanation is that Aberforth was working with Snape, and that Albus may have told him of Snape's true allegiance before he died.
Because of the tendency for families to all be sorted into the same house, it's possible Aberforth was also a Gryffindor, although his behavior (and reticence to fight) suggests otherwise.
By Harry Potter and the Deathly Hallows, it's a stretch to call Draco a villain anymore. We just watched — or read — him struggle to reconcile his choices and morals in The Half-Blood Prince. He can no longer justify his actions, and is far more aware of the evil he was born and raised into.
When Dobby's last words before dying in Harry's arms are "Such a beautiful place, to be with friends. Dobby is happy to be with his friend, Harry Potter."
In the film, she only hugs Harry, and just gives a hesitant handshake to Ron (Note: This was the result of Emma Watson being hesitant to hug both Daniel Radcliffe and Rupert Grint in public view, with her hugging Radcliffe during filming having to be frozen for a few seconds to get the desired effect due to Watson ...
They know she's an impostor. They've been warned", so obviously the request for the wand was unexpected even to him. It's thus pretty safe to conclude that the real Bellatrix had reported her wand stolen and alerted Gringotts prior to the trio's attempted break in.
Death. Fifty-three years after his defeat, Grindelwald was slain in his prison cell by Lord Voldemort, who was searching for the Elder Wand for himself. It was only during the confrontation in Grindelwald's cell that Voldemort learned Albus Dumbledore had claimed the wand long ago.
The character had previously referenced his brother Aberforth, and in Harry Potter and the Deathly Hallows, it is revealed that Albus is three years older than Aberforth.
Dumbledore tells Newt Scamander (Eddie Redmayne) that in 1899, during the same summer that Albus fell in love with Grindelwald, Aberforth also fell in love with a woman from Godric's Hollow. They had a baby boy together, but the woman was sent away before she gave birth, and Aberforth never got to be a father.
