I always wondered why this community was called Harmony. From the Geographical Place Names of Prince Edward Island by Alan Rayburn, Page-61, he explains.
"Harmony: 7 mi SW of Tyne Valley in Lots 13 and 14. Selected for a school c1875 because the settlers of many nationalities - French, Irish, Scottish, English, Dutch - got along peaceably. PE 1907-1914, Formerly called Line Road."
