Taking a micro-historical approach, this paper explores the business activities of Elizabeth Carter and Elizabeth Hatchett, two married women who operated together as pawnbrokers in London in the early decades of the eighteenth century. Based on a protracted inheritance dispute through which their extensive dealings come to light, the discussion assesses married women's lending and investment strategies in a burgeoning metropolitan economy; the networks through which women lenders operated; and the extent to which wives could sidestep the legal conventions of ‘coverture’ which restricted their ownership of moveable property. It is argued that the moneylending and asset management activities of women like Carter and Hatchett were an important part of married women's work that did not simply consolidate neighbourhood ties but that placed them at the heart of the early modern economy.
