Anthony Henday
This trip, and later ones, took Henday across much of the prairies of what is now Saskatchewan and Alberta and his journal shows that he brought a lot of trade to York Factory. Records show that some of the trade also went to the French at Fort Saint-Louis (Fort de la Corne)  and Fort  Paskoya which were on the route to Hudson Bay. He left the service of the HBC in 1762 largely because his efforts for the company, at least in his estimation, had not been properly recognized.
