History & local legend
John 'Yank' Brown belonged to a band of thieves operating along the Huntingdon, Cambria and Indiana Turnpike. Around Armagh in Indiana County, his name became attached to a treasure and ghost story later preserved by county historian Frances Strong Helman.
In the legend, Brown kept stolen horses in a cave until they could be sold. After his death, people began searching for money supposedly hidden in the same place. Their searches produced another kind of encounter: the sound of horses galloping along the old pike toward the hideout, as though Brown were still bringing stolen animals in for shelter.
