The area was originally settled in 1792 as part of the historic Glengarry County in which many Scottish emigrants settled from all over the Scottish Highlands due to the Highland Clearances. This first wave of heavy migration lasted till 1816, emigration still continued afterwards into the early 20th century but in a slower pace. Many of these migrants came from the Inverness-shire area of Scotland specifically. Canadian Gaelic / Scottish Gaelic has been a spoken language in the area for over four centuries [1792?]. Kenyon, which was part of Charlottenburgh Township until 1798, was named for British judge and politician Lloyd Kenyon, 1st Baron Kenyon, and Lochiel, which was part of Lancaster Township until 1818, was named for the Lochiels of Clan Cameron.

Alexandria and its nucleus Priest's Mill, built in 1819, were named for the Catholic priest Alexander Macdonell, who resided at St. Raphael's and later became the first bishop of Kingston.

Development in the region was significantly spurred by the development of a railway link between Ottawa and Montreal in the early 1880s. Maxville, Alexandria and Glen Robertson, in particular, became key railway hubs for farmers in the area.

Maxville was first incorporated as a village separate from Kenyon Township in 1892, and Alexandria was separated from Lochiel Township in the early 1900s.
