Both Samuel L. Purdy, owner of the Purdy Milling Company, and Hudson P. Gould, Reeve of Cramahe Township, showed their pride of place by paying for highly detailed illustrations of their homes for inclusion in the 1878 Illustrated Historical Atlas.
The origin of Purdy's Mill is linked to Joseph Keeler (1788-1855), the founder of Colborne and Castleton, and is believed to date to the 1830s or 1840s. Purdy's Mill was not included in this image, perhaps the artist's choice to simplify the landscape and create a picturesque view. Castleton Mills, however, featured prominently in the landscape as important local building and business. Piper's Creek powered the mills.
Gould's brick farmhouse dates to 1873 and was built in the popular Gothic Revival style of architecture. Both illustrations portray Castleton as a thriving community surrounded by well-tended countryside.
