It can be assumed that everyone who didn't die who was on the "good side" (all Death Eaters besides the Malfoys were either killed or imprisoned in Azkaban, which got rid of Dementors but still made it harder to escape) moved on to nice careers and marriages and was happy. "All was well" as there were no dark forces from 1998-2017. Harry became an auror, then head of the auror office and married Ginny. They had three kids named James Sirius, Albus Severus, and Lily Luna. Ginny first played on the Holyhead Harpies and then became the Quiddtich corespondent for the daily prophet. Hermione was the only one of the trio who went back to school an extra year to achieve her NEWTS, and she was at first in the Department for the Control and Regulation of Magical Creatures, improving house-elf standards, and then moved to the Department of Magical Law Enforcement, where she got rid of Pro-Pure blood laws. She of course married Ron, who originally worked in Weasley's Wizard Wheezes and then too became an auror. He also is known to have gotten a muggle driver's licesnse (while confunding the tester) in 2017. Their kids are named Rose and Hugo. Neville married Hannah Abbott who was the land lady of the Leaky Cauldron, which they lived above, and he became the Herbology Teacher at Hogwarts. Luna became a wizarding naturalist and married fellow on Rolf Scamander, having two sons, Lorcan and Lysander. Hagrid was known to still work at Hogwarts and want Harry's kids over for tea like he did for him. He never married Madame Maxine or anyone else. All of the Weasleys got married and had childen with the exceptions of Charlie and Fred (because the latter was dead). Bill and Fleur had three kids called Victorie (because she was born on the anniversary of the Battle of Hogwarts), Louis, and Dominque. Percy married a women called Audrey and had two kids named Molly (after his mother) and Lucy. George married Angelina Johnson (his late brother's ex girlfriend) and had two kids-one named after Fred and one named Roxanne. Malofy married Astoria Greengrass (Daphne-a Slytherin girl in their year's younger sister) and had a son named Scorpious. His hair line was receeding and he gave the trio a curt nod at King's Cross. There is a lot of Scorpius/Rose fanfiction. Dudley had three kids, and he and Harry were on "christmas card terms" and visited occasionally which no one liked. One of those kids was supposed to be a wizard but it never happened. Kingsley went from acting Minister of Magic to real one. He helped abolish the Pro-pure blood ways. McGonagall became Headmistress after the battle, but had retired by 2017 as she was "getting on a bit." Lupin and Tonk's son Teddy lived with is grandmother but as Harry's godson was over at their house for dinner like four times a week. He was Victorie had a romantic relationship by 2017, when he had graduated and she was in her last year. He was not a werewolf like his father, but he was a Metamorphagus like his mother, having turquoise hair. That help?
