History Kettleby was established no later than 1825, when Jacob Tool of Pennsylvania purchased in a wide ravine, including a stream. He built a sawmill powered by the stream's flow, but little other development occurred in the area. It was the industrious Septimus Tyrwhitt, who purchased of Tool's property in 1842, that spurred development of more mills and the eventual settlement of Kettleby. Early settlers often referred to it as Tyrwhitt's Mills, in honour of Tyrwhitt. However, he disapproved of the name, and his wife subsequently named the hamlet Kettleby, after the Tyrwhitt family ancestral home in Lincolnshire, England. That the name Kettle Bee derived from the construction bee of raising Tyrwhitt's mill, which drew many men from surrounding villages, is a local urban legend. Tyrwhitt was named reeve of King Township in 1852. On August 6, 1851, the first post office was opened, and was styled Kettleby Mills, Canada West. In September 1859, it was renamed Kettleby, by which name it is still known today. Kettleby had the largest membership in the Sons of Temperance society in Upper Canada, with over 200 members, and was "one of the strongholds of the temperance movement in the mid-19th century". Temperance Hall, a gathering place of the Sons of Temperance, was built in 1850. It was transported to Black Creek Pioneer Village in order to preserve it. The hamlet's first distillery preceded the movement by nearly a decade, having been erected in 1843, and numerous establishments throughout King were licensed to serve alcohol, including two hotels in Kettleby.
