Auguste Frank Barrow Burt was Incumbent of Trinity Anglican Church on Chester St. East in Durham, Glenelg Township, Grey County from January 1891 to March '93.  He also held services in a schoolhouse 6 miles south of there in Egremont Township, just south of Varney on this map. (The site is now a cemetery bearing a sign in one area designating the old schoolyard.)  Durham itself is now part of the amalgamated municipality of West Grey.
The Burts then moved to Shediac Cape, New Brunswick.
