I am not related but came upon your message. In a book called A History Of Simcoe County by A F Hunt (1907) there are several brief notes regarding Wellesley Richie who was stationed in 1832 near Bass Lake (Oro Township) another reference indicates Coldwater Road. Anoher reference Donald Shaw of Sunnidale was related to Wellesley Richey by marriage. The last reference refers to the memoires of Rev. Thomas Williams published by the Simcoe County Pioneer and Historical Society in 1909 which gives an account of the arranging of settling upon the land in Sunnidale the Rev Williams being a member of Mr Richey"s party. There is a variance in the spelling of Richie - Richey but in each case Mr. Richie is referred to as the Government agent. Hope this might lead somewhere for you.
