John Langton 1808-1894
Born in Lancashire, England, Langton graduated from Cambridge University in 1829 and emigrated to Upper Canada in 1833. He purchased some 200 ha of land in Fenelon and Verulam Townships, where he was one of the first settlers and built "Blythe House" near Fenelon Falls in 1837-38. From 1851-55 Langton represented the Peterborough area in the legislative assembly of Canada. He was appointed auditor of public accounts in 1855 and from 1867 to 1878 served as auditor general. His collection of letters, later published under the title of "Early Days in Upper Canada", provides a valuable account of pioneer settlement.
