Around 1891, the town was the scene of an attack on a young Ariana Dumbledore by three Muggle boys who had spied on her innocent, uncontrolled use of magic. The boys tried to force Ariana to show them her trick, but when she was unable, they turned violent, utterly disrupting Ariana's magical ability. As a result of the attack, she became unwilling to use magic, and the resulting magical build-up caused her to have violently powerful magical accidents. Her father Percival attacked the boys and was subsequently sent to Azkaban for crimes against Muggles. Despite the instability of Ariana's condition, she was not detained at St Mungo's Hospital for Magical Maladies and Injuries, as her father never revealed the reason for his attack on the Muggle boys in his defence.
About a year after the attack on Ariana, Kendra Dumbledore relocated herself and her three children, Ariana, Albus and Aberforth to Godric's Hollow, where she isolated the family in an attempt to hide Ariana's disability.
The village might be named after the English market town Stow-on-the-Wold, in Gloucestershire. "Wold" is an archaic word for a grassland, while "mould" is an alternative spelling for "mold". In the context of the town's name, "stow" most likely means "a place", but the word is also a verb meaning "to store over a long time".
