Kilmarnock rests with a quiet permanence near the slopes of the Brandy Hill, cradled by the persistent currents of the Rideau River. It lies 7.4 km east of Smiths Falls, ON (from Smiths Falls, ON: bearing 99°T), and is situated 7.6 km west-south-west of Merrickville. The land here holds the memory of early settlement, where the water once dictated the movement of goods and the slow expansion of homesteads. Life in Kilmarnock keeps a measured pace, observing the changing light as it catches the reeds along the riverbanks during the long Ontario afternoons. While South Mud Lake sits a distance away as a silent, inland neighbor, the life of the locality remains drawn to the river’s edge. The soil and the nearby terrain support a persistent, quiet industry, reflecting a history built on the necessity of the land and the endurance of those who first cleared the timber to make a home.
