Historic plaque located at the former site of the community of Killyleagh near the intersection of the 5th Sideroad and 6th Concession. The plaque features a photo of the S.S. #6 schoolhouse, as well as the logos of the Town of Innisfil and the County of Simcoe. The sign reads: "Located around this site was the country hamlet of Killyleagh. It was first settled in 1853 by the Grey, Scroggie, and Sharpe families who arrived in Canada from County Sligo, Ireland. Members of the community first suggested the name "Scroggietown" for the hamlet, but it was thought to be too cumbersome. The name Killyleagh was suggested by James Scroggie after a town in his native Ireland. The first log school (S.S. #6) was opened near here in 1857 on land donated by the Sharpe family. In 1910 the school was remodelled and bricked and still stands today. A Post Office operated in the hamlet between 1879 and 1903."
