County in Ontario, Canada, between the Saint Lawrence and Ottawa rivers; settled by Highlanders.
These were originally of Glengarry, Scotland, and had been driven by fanaticism, during the American Revolution, from their New York settlement in the Mohawk Valley.
They were joined by two groups of Catholic Highlanders from Glengarry, Invernessshire, and other districts of western Scotland: one brought out by Reverend Alexander Macdonell (Scotus), in 1786; the other in 1803-1804, by Reverend Alexander Macdonell, afterwards first Bishop of Kingston.
The Glengarry Fencibles, reorganized from the Catholic regiment of that name raised by the last named in Scotland in 1794 and disbanded in 1802, fought against America in the War of 1812, with Father Macdonell as chaplain.
