Mark Fothergill son of William Best Fothergill worked from 1752 – 1800, he had been apprenticed to a Benjamin Collier and his wife Elizabeth in 1745 (so likely born late 1720s?). The date of his fathers death being the same year as he started his apprenticeship does not help us to understand how his father worked. Mark is also unlikely then to have been very active when M Fothergill & Sons was formed (trading perhaps 1793 – 1845).
