Such is the greatness of Rowling’s imagined world she has even provided us with information about what happened to everyone after the series ended, even more than the epilogue. There is absolutely no room to post everything that has been revealed but the links at the end are a great starting point. I also suggest perusing Pottermore where more information can be found. I did find a great starting point; a delightful person on Tumblr compiled a list of things that happened in the wizarding world after the end of the books which I’ve included here. What’s important to note is that these were mostly written before Cursed Child which according to Rowling is to be considered canon. I myself am still undecided on that.
- Azkaban no longer uses Dementors as guardians.
- George Weasley married Angelina Johnson and had two children named Fred and Roxanne.
- Harry made sure that the Wizarding world knew that Snape was a hero and on Dumbledore’s side.
- Slytherin House became more diluted and was no longer solely pureblood; however its dark reputation lingers.
- Harry lost the ability to speak Parseltongue.
- Umbridge was arrested, interrogated and imprisoned for crimes against Muggleborns.
- The Resurrection Stone is now buried in the Forbidden Forest after being pressed into the ground by a centaur’s hoof.
- Voldemort’s curse on the DADA position at Hogwarts has been lifted.
- Viktor Krum fell in love with a woman back home in Bulgaria.
- The Death Eater’s Dark Marks eventually faded to look like a scar. It will no longer burn or hurt.
- The Quibbler is back to publishing articles about the lunatic fringe and is appreciated for its unintentional humour.
- Members of the DA still have their coins, as they are like badges of honour.
- Neville Longbottom worked as an Auror before moving on as the Herbology professor at Hogwarts.
- The remaining Death Eaters were killed or imprisoned in Azkaban for their crimes, with the exception of the Malfoys.
- Luna Lovegood married the grandson of the Newt Scamander, author of Fantastic Beasts and Where to Find Them.
- Firenze survived his wounds and was welcomed back into the Centaur herd.
- Harry will never become Headmaster of Hogwarts since an academic career just isn’t him.
- Hagrid was still working at Hogwarts by 2017, at 88 years old.
- Draco Malfoy really cares about his son, Scorpius Malfoy. He is growing him up to be a better person than he was.
- Centaurs realised that pro-human leanings were not shameful.
- Draco and Harry never became friends, but they did come to understand and appreciate each other better.
- Hermione tells Scrimgeour that she is not planning to embark on a career in Magical Law but that’s actually where she ends up.
- After his death, Voldemort is forced to exist in the stunted infant-like form that Harry sees in the King’s Cross-like Limbo.
- Harry would take his family to visit Dudley’s when they were in the neighbourhood (occasions dreaded by James, Albus and Lily).
- Aberforth is still at the Hog’s Head “playing with his goats”.
- The number of Dementors have been greatly diminished because despair and degradation have been lessened in the world.
- Arthur Weasley fixed Sirius’ motorbike and gave it to Harry.
- Nineteen years after the Battle of Hogwarts, the school for witchcraft and wizardry is led by an entirely new headmaster (“McGonagall was really getting on a bit”) as well as a new Defence Against the Dark Arts teacher. That position is now as safe as the other teaching posts at Hogwarts, since Voldemort’s death broke the jinx that kept a Defence Against the Dark Arts professor from remaining for more than a year.
- Hagrid never married, although he had a relationship with a giantess.
- Kingsley Shacklebolt became the Minister of Magic after the Second Wizarding War.
- Harry will not train to be an animagus; his “energies are going to be concentrated elsewhere and he’s not going to have time to do that.”
- Audrey Weasley is wife of Percy Weasley, and they have two daughters, Molly and Lucy.
- In the aftermath of the war, the Order was disbanded once and for all.
- Luna has twin boys named Lorcan and Lysander with Rolf Scamander and apparently travels the world, looking for mad creatures.
- Hermione advanced the rights of magical creatures and eradicated the old pro-pure-blood laws in the Department of Magical Law Enforcement.
- The head of the Auror Office as of 2007 is Harry Potter.
- Lavender Brown was attacked by Fenrir Greyback. Hermione saved her but she was already injured. What happened to her later on was never revealed.
- Neville Longbottom’s students were impressed when he showed them his Dumbledore’s Army’s Coin.
- Harry, Ron and Neville didn’t return to Hogwarts for their 7th year. They went straight to get training as aurors and Neville went to work as an auror before becoming a Professor.
- Harry sometimes visits Hogwarts to give talks on DADA.
- Hermione is James’ godmother.
- Hermione Granger was the only member of the trio who returned to Hogwarts to complete their seventh year.
- Ron worked with George in WWW for some time and then became an Auror.
- Ginny became a professional Quidditch player for the Holyhead Harpies and become the senior Quidditch correspondent for the Daily Prophet.
- After the war, Hermione found her parents in Australia and restored their memories.
- Harry eldest son James Sirius started at Hogwarts on 1 September 2015 and is in Gryffindor
- Harry is greying aged 35 and sports a nasty cut over his right cheekbone.
- Fluffy was repatriated to Greece after he was released into the forest
- Teddy Lupin became Head Boy
It’s quite an impressive list, and gives some great closure about what happened to everyone. The links below include a bunch of other facts that have been released post novels and films by Rowling in interviews and on Twitter. Some are a few years out of date, but interesting nonetheless. You can see this was also whilst Rowling was writing Fantastic Beasts.
