A.D. & W.B. Roe, known as the Roe Brothers, were prominent 19th-century cartographers based in Saint John, New Brunswick. Their base maps were from British Admiralty charts and National Surveys using rectangular polyconic projection. They are best known for publishing the highly detailed Atlas of the Maritime Provinces of the Dominion of Canada in 1878, which is considered the only 19th-century atlas covering the Maritime provinces of New Brunswick, Nova Scotia, and Prince Edward Island.
