Regarding the sentence "Thus Potter resided in what was then the Canadian capital of Montreal, Lower Canada." 'Lower Canada' ceased to exist in 1841: https://en.wikipedia.org/wiki/Lower_Canada. And Quebec City was the effective Canadian capital at the time, with Ottawa capital-designate and under construction: https://en.wikipedia.org/wiki/Province_of_Canada#Capitals216.222.180.142 (talk) 16:30, 3 June 2020 (UTC)Reply
