Christopher Dufrost de La Jemeraye

In the spring of 1733, he and Jean Baptiste headed down the Winnipeg River to set up a post in the Lake Winnipeg area. Ice stopped them and La Jemeraye returned to Fort St. Charles while his cousin established a small temporary fort named La Barrière. La Jemeraye continued as an important participant in La Vérendrye's exploration and fur trading activities. He and Jean Baptiste de La Vérendrye built Fort Maurepas about six miles north of present-day Selkirk, Manitoba, in 1735. Traveling from there to Fort St. Charles via the Red River/Savanne Portage route, La Jemeraye, who was very ill, died at the junction of the Red and Roseau rivers. The Forks is the site of present-day Winnipeg. An interesting and important contribution of Christopher Dufrost relates to his skill as a cartographer. He produced the first French map of the west in 1733. It was of high quality and the final copy was produced, at a later date, by the engineer, Gaspard-Joseph Chaussegros de Léry. His sister was the sainted Marie-Marguerite d'Youville, Catholic nun and foundress of The Sisters of Charity of Montreal.

Christopher Dufrost de La Jemeraye is recorded as explorer and cartographer.
