The latest post on the London Historians’ Blog, a reprint from an August 2020 members’ newsletter is about some of the 2,500 pamphlets being reviewed in a volunteer project with the Royal Institution.
The article lists the titles of some of the pamphlets. One that attracted my attention was Letters from the Dorking Emigrants, who went to Upper Canada, in the Spring of 1832. Google revealed that it could be viewed at the Canadiana.ca collection — with 52 full-text searchable pages.
Was your ancestor amongst those mentioned?
I wonder if these are in TONI — The Ontario Name Index from OGS?
I suspect these may be Petworth settlers, although Dorking is 50 Km from Petworth.
