Likely Jesse will be better known for his trading post at Chisholm's spring near Ft Arbuckle,he owned interest in both. A family lore has it and it was talked also in that- 1939 interview on his death in 1868, was a accident/unexpectedly is still some what a mystery.
A New book wrote- who explained who both JESSEE Chisholm's (differ spelling) Texan cattleman friend of New "Billy the Kid" stated that the Indian Trader Jesse Chisholm died from eating bad Bear fat meat? This agrees whith what my Gf told me in the 1970 he died from eating
posioned-(Old-spoiled) bear meat from the Indians.
In these day they made lard out of bear fat also, they likely would not have under stood what was wrong with him but it sounds very painful.
