In the aftermath of the riots, definitive evidence is hard to come by, and some doubt if Jenny Geddes had even started the fight or if she even existed, but she remains a part of Edinburgh tradition and has long had a memorial in St Giles.
Note: The story "Jenny and the Kings' Men" assumes that Jenny Geddes did exist. While it it does not directly comment on whether she actually did what she was alleged to have done, it is fairly clear that the characters who are aware of it believe that she did.
Jenny and her daughters managed to escape the English and found safety with the Edinburgh chapter of the Committees of Correspondence, where she met Otto Artmann. Shortly afterward, Otto took her to meet Alexander and Julie Mackay, knowing that Jenny wouldn't really believe in people from the future unless she met one. Julie explained that in the OTL, Jenny was remembered for throwing a stool at a minister for using Anglican rites before a Presbyterian crowd. This act was the spark that started a major riot that spiraled into the start of the English Civil War. While skeptical at first, Jenny came to believe Julie's words about her role in history.
Not long afterward, Jenny was tracked down by English forces bent on assassinating her. She personally killed William Hignall, leader of the English troops, with a .22 caliber revolver Julie had given her. She also killed one of Hignall's troopers by throwing a stool at him, breaking his neck.
Afterwards, Jenny decided to throw her lot in with the CoC and fight against corrupt aristocrats.
