I am interested in the chairmaking trade in Canada, so all chairmakers are part of my research. I found John listed in Lovell's Directory of 1857 (chairmaker, Cavan St., Port Hope), and Thomas Clouston is listed in Mitchell's Directory of 1864 (chairmaker, Cavan st. Port Hope). John is listed in the industrial census in 1871 as proprietor of a cabinet factory in the census district of Ontario North (Ontario County rather than province) and subdistrict Brock (twp.) That is all I have. I would appreciate anything that you are willing to share that pertains to his chair factory or his chairs.
