This fonds consists of a narrow, hardbound ledger book containing handwritten entries of accounts held by customers of an unknown merchant identified as “E.H” (possibly E. Hall), 1826-1831. E.H. was likely based in the vicinity of present-day Windsor, Ontario. The ledger presents itemized lists of goods purchased and amounts owing or paid, under each customer’s name. Roughly two-thirds of the volume is unused. E.H.’s customers came primarily from Essex and Kent counties and Detroit, Michigan, but also elsewhere along the upper Great Lakes, including Drummond Island. Both male and female names are present, and some customers’ occupations are given as well, including blacksmith, miller, distiller, cooper, cook, merchant, labourer, crevier, regimental sergeant, ship’s carpenter, seaman, sailor, engagé, servant woman, and inhabitant. Many customers are French-Canadian; one may have been Black, and another Indigenous.
