Charles Lagasse, or Lagace (1775-?) joined the North West Company (NWC), under the leadership of McTavish and Frobisher, earlier than 1792, but we know for sure he was engaged by them on March 28, 1792.

Charles Lagasse went on to become a long time NWC employee who spent much of his time in the Columbia River plateau area with David Thompson. 


From: New light on the early history of the greater Northwest: the manuscript journals of Alexander Henry, fur trader of the Northwest Company and of David Thompson, official geographer of the same company 1799-1814, AND from Lives Lived West of the Divide: A Biographical Dictionary of Fur Traders. Working West of the Rockies, 1793-1858, by Bruce McIntyre Watson, we learn:


As early as April, 1800 Charles Lagasse was with David Thompson on the Upper Saskatchewan River.


From October 5th through the 23rd 1800, Charles Lagasse went with David Thompson to the Kootenay Indians.  Thompson set Charles up with trade goods, so he could winter with the Kooteneys during the winter of 1800-1801.  In the spring of 1801, Charles Lagasse returned to Rocky Mountain House to meet with Thompson.


From: Parkways of the Canadian Rockies: A Touring Guide to Banff, Jasper, Kootenay, and Yoho National Parks, we learn that the first white men to go up the Saskatchewan River and over Howse Pass were two North West Company voyageurs named Le Blanc and La Gassi (Lagasse), who were sent by David Thompson to winter on the west side of the Rockies with the Kootenay Indians in 1800.


On November 7, 1808, Charles Lagasse went with David Thompson on a journey from Boggy Hall to Kootenay House.   


Between 1808 and 1810, Charles Lagasse was with David Thompson in the Rocky Mountains.


In the spring of 1810, in the Saleesh area, David Thompson paid Charles Lagasse for the hire of three horses, but on May 17th 1810, David Thompson attempted to force him to duty for which Charles Lagasse said he was not fit, so Thompson listed him as a deserter.


On June 22nd 1811, Charles Lagasse reappears with David Thompson at Ilthkoyape Falls (also known as Kettle Falls) on the Columbia.  Thompson named the falls Ilthkoyape Falls and the Indians who fished there Ilthkoyape Indians. These are among the forebears of Indians who are today organized as the Confederated Tribes of the Colville Reservation.


On August 29th 1811, Charles Lagasse went south on the Columbia River with the David Thompson expedition as they headed up the Columbia after stopping at Astoria.


In 1812, Charles Lagasse re-engaged on a two year contract in the Columbia (to be free in Montreal in 1814).


In 1813-14, Charles Lagasse wintered at Fort George (Astoria).


On April 4th 1814, Charles Lagasse was noted as being a bowsman on John Clark’s canoe on the brigade to Fort William and Montreal.


Charles Lagasse returned to the Columbia area and continued his association with the NWC until 1821, when his contract was transferred to the Hudson’s Bay Company during its merger with the North West Company.


In 1821, he was listed as a ‘freeman’ (meaning his contract had expired).


After 1822, Charles Lagasse does not seem to have been engaged by the HBC.  Had he expired?  His date and place of death remain unknown.


Bruce McIntyre Watson's work suggests that Charles may have married a Flathead Indian woman: "Charles La Gasse appears to have taken as a wife, Emme, Flathead (c.1795-1855).  Two of their children may have been Pierre (c.1815-1882) and Josette/Suzette (c.1812-1896) although oral tradition indicates that “Pierre”, a brother of Charles, was the father of the two children but no such “Pierre” appears in any extant records."
