Conclusion
THE FUTURE—After her cousin destroyed the last Horcrux, Belle went to Neville and asked to see their daughter. It hurt that little Nellie had forgotten her biological mother and now called Neville's wife "Mommy," but slowly Belle was able to reestablish a relationship, and eventually, she and Neville worked out a co-parenting agreement.
Then Belle turned her attention to the legal system. Using her intelligence and influence, she was able to convince the skeletal Ministry to free everyone who had been wrongly imprisoned, including George's father. This act opened the doors of communication for them, and they began to rebuild their friendship, which grew into a romantic relationship, eventually getting married. Though it was rather late for them to be starting a family—they were both in their thirties—they went on to have four children: Two boys and a pair of identical twin girls.

Swan and Dumbledore's wedding wasn't the "Wedding of the Century," but it was undoubtedly memorable. She walked down the aisle in the most haphazardly constructed white dress that she could find, and the entertainment for the reception was the most eccentric imaginable—Luna Lovegood coordinated the whole day.
After they got married, Swan and Dumbledore took a cross-continent road trip with Erick, so he could see the world. They finally settled down in Godric's Hollow when Erick began his schooling at Hogwarts, at which point Swan introduced Hagrid to his son. Dumbledore also wanted to slow down a bit, partially because at one hundred and thirty years old, he wasn't as spry as he had once been.
After Dumbledore's passing in 2032, Swan started travelling the world again, though she was now in her fifties. She occasionally came home to see her son with his wife and kids.

Alina's marriage got off to a rocky start, but after time and counseling, her and Tom were able find a healthy middle ground and became coequal rulers. Two decades into their reign, they tired of listening to complaints from their subjects, so they handed the government of the Ministry off to Cornelia Longbottom and went into the business of beauty products with Lucius Malfoy.
Ultimately, Alina became an icon in the Pureblood community.
She and Tom never had children—neither of them wanted progeny—but they enjoyed long, healthy lives. After eighty years of marriage, they died in their sleep, wrapped in each other's arms.
And the world spun on.
