The "shoes" story gets brief mention in Brenda A. Ayres' Persephone in the River Phlegethon; or, the Women of Gettysburg, (2009) Faculty Publications and Presentations, Liberty University.
In addition to relating the story that is the focus of this thread, as part of a thumbnail sketch of Adams County the author notes that a number of men made their living from shoes due to the presence of tanneries, but that there was no shoe factory.
