South Rosedale was first settled by Sheriff William Jarvis and his wife, Mary, in 1826 after Jarvis inherited his father's home there two years earlier. Mary Jarvis, the granddaughter of chief justice and loyalist William Drummer Powell frequently walked and rode on horseback around the trails for that formed Rosedale's meandering streets (which are one of the area's trademarks). She named the estate "Rosedale" as a tribute to the abundance of wild roses that graced the hillsides of their estate. The Jarvis estate was subdivided in 1854 and became Toronto's first "garden suburb". The Jarvis Family sold the Rosedale homestead in 1864, which led to the residential development of the area soon after, including the extension of Cluny Drive.
