Flora Yaxley forgave her husband. She did the research for finding and destroying the other suspected Horcruxes in her sparse free-time. As Voldemort had taken fourteen years to regain a body the first time around no one was in a particular hurry. Flora suspected Harry Potter to be the last, unintentional of seven Horcruxes, but as the young man had grown up to be an even-tempered and responsible adult under the tutelage of Remus Lupin and Sirius Black – Pettigrew had gotten himself captured shortly after snakeface's implosion – she reasoned that the miniscule piece did not bother Auror Potter.
Severus Snape was said to have given Dumbledore a two-fingered salute during a staff meeting before leaving Hogwarts and Britain for good. He was rumoured to live a life of leisure on Oahu, doing research when the mood suited and otherwise peddling potions to hula dancers, with most of whom he was on a first-name basis.
Dolohov became godfather to the Yaxleys´ fifth child, a girl finally, who was named Elizabeth Victoria. Elizabeth for Her Majesty and Victoria because of their victory over Voldemort, a victory no one safe the conspirators and the queen knew about. Well, Severus Snape might suspect something.
After regaining the use of his magic, a process that took over a year, Antonin devoted his free time to draft wards to protect the queen and her family. One day the queen confided in Antonin that she was especially glad about the amulets he had crafted for Diana and the boys against paparazzi as she had feared the constant hounding of them would have led to very unpleasant situations.
Antonin Maksimovitch Dolohov stayed in Her Majesty's employ. After his stint as an undergardener he became one of her personal security guards. He never married and stayed in his small room under the roof. There might have been a dalliance with the head-housekeeper but as senior staff of Her Majesty they knew how to be discreet.
In 2021 he was never far from Her Majesty's side during what was her darkest day, the day she had to bury her husband of 74 years.
