Bertram and Cecilia Couldery travelled through Belleville in the 1880s. They decided to keep a second home here. They became close friends with the Docter family of Belleville. Ann Docter (1868-1956) returned to England with them in 1890s. She later inherited their collection of fine art and furnishings. In the 1950s she donated the collection to her hometown of Belleville.
Many of the paintings on display at Glanmore are attributed to the Bertram and Cecilia Couldery. Cecilia specialized in painting portraits. Her husband Bertram created many landscapes. Bertram also copied other artists' work as a way to improve his skills. Bertram's older brother Horatio Henry Couldery (1832-1918) was a noted British artist of animals.
42 animal paintings by Horatio H. Couldery give Glanmore's Couldery Collection international significance.
