6 Quoted in Forde, “Derbyshire Quakers,” vi.
7 Pratt, “English Quakers and the First Industrial Revolution,” 53-65; especially helpful is chap. 3, “The Geography of Nonconformity,” which concludes that “the Quakers had always been a northern religion.” By the end of the 17th century, there were Quakers in every English county and city. In the 18th century, many Quakers moved south to London and Birmingham. But the largest number remained north and west of the River Trent.
