Non-native settlement in the region dates to ca. 1740. In 1754, prominent soldier and land owner Colonel Charles Broadwater settled within the town boundaries. Broadwater's son-in-law, John Hunter built the first recorded house there in 1767, naming it Ayr Hill (recalling his birthplace, Ayr, Scotland.) That name was subsequently applied to the tiny, developing community.
