Dutchess County, New York patriots forced colonists loyal to the British government to flee north into what became Ontario.
The Loyal Rangers were created on November 12, 1781 from a number of smaller military units including the Loyal Americans
They were led by Edward Jessup (1735). The Jessups had lived in Connecticut for several generations, but moved to the “Upper Nine Partners Patent” in Dutchess County, New York in 1744.
They were usually stationed at Sorel or Verchères and provided garrisons for posts at Yamaska, Rivière-aux-Chiens, Île aux Noix, and Dutchman’s Point (near Alburg, Vermont).
The rangers were disbanded on December 24, 1783.
After the war, Jessup’s Rangers were allotted townships number 6 (Edwardsburg), number 7 (Augusta), and part of number 8 (Elizabethtown), all on the St Lawrence, as well as No 2 (Ernestown), west of Cataraqui (Kingston)
Brockville, Ontario was called Elizabethtown. The area was first settled by English speakers in 1785, when Americans who had remained loyal to the crown fled to Canada after the American Revolution.
