These two buildings are fine examples of mid-Victorian commercial buildings from the early 1870s, a time when Prescott was experiencing a very impressive period of growth.

These properties form one harmonious whole with the Baines building. These three buildings were constructed according to the same basic design, with importance placed on the preservation of the façade of all three. 

Grocers, Thomas and Marcus Keitly bought their King Street property in 1871. It is believed that all three properties, including the Baines building, were constructed in 1874 since the keystone in the Boyd building bears the inscription "1874". In 1878, the Canadian Illustrated News described the building as a fine block which would do credit to any city.
