Chief Trader John Edward Harriott – As John Rowand's second-in-command, and also Rowand's son-in-law, Harriott was a valuable benefactor for Robert Rundle. He assisted Rundle in the translation of a prayer book to Cree language, and was known to have helped the mission's endeavours in various ways. He was the first person on record to be married by Rundle in the Saskatchewan District, having sanctified his wedding vows to John Rowand's daughter Nancy in 1841 (whereas he and Nancy had been engaged in a country marriage since the late 1830s).
