Some of the information may be in the book Official History of the Cornwall Cheese and Butter Board: an Historical, Biographical and Descriptive Account of the Dairying Industry in the Cornwall District, with Especially Written Articles by Prominent Dairying Experts, by H.M. Stiles. Cornwall, 1919.
The Cornwall Public Library probably has a copy in its local history collection. A microfiche copy (CIHM #84484) can be purchased from the Canadian Institute for Historical Microreproductions in Ottawa (e-mail: cihmmicmh@nlc-bnc.ca)
