Surprisingly, I find few accounts of individual Indians of the Kankakee River Valley. Mingo is the exception.
The most detailed information about him comes from Maj. Samuel L. McFadin as told to him by Killbuck and LaBonta.
Killbuck and LaBonta first met Mingo near the "Great Bent of the Missouri River." That would be near today's Kansas City. It would have been soon after the Potawatomi were removed from Indiana to Kansas in the late 1830s. Mingo was "swimming in a small stream when some of the Pawnees suddenly came upon him capturing Mingo."
Because of Mingo's youth and striking figure he was "placed with the family of a principal chief of the Tetons, a branch of the Pawnees" and gave him a more respected place with his captors.
McFadin wrote: "It is frequently the lot of captives to become servants, and assigned to menial offices constitute to the employment of women. This position was very mortifying to the Indian pride of Mingo, who the Indians had named Doranto. But he was somewhat reconciled to it, as it threw him into the company of a beautiful daughter of the chief whose name was Niargua. It gave him frequent opportunities of walking, talking and laughing with the Teton damsel whose heart it was his good fortune to gain a complete victory."
The relationship between Mingo and Niargua was noticed and her father was informed of the bond. Niargua's father flew into a rage and he threatened to "shoot an arrow through Mingo for is bold pretentions." As in the case of all youth this seemed to only strengthen the two lovers determination.
It turned out that another brave was vying for Niargua's attention. This rival was constantly taunting Mingo until he "demanded satisfaction. They agreed to settle their difficulty by single combat, and the weapons to be used were war clubs and knives."
Mingo killed his adversary. With this victory Mingo was accepted as a adopted son of the band, but Niargua's father would still not allow Niargua to marry Mingo.
The two decided to escape to his Potawatomi camp along the Missouri. After a couple of days of hard riding, Mingo and Niargua reached Killbuck and LaBonta's camp. The two trappers made note they were "much fatigued and wayworn." Killbuck and LaBonta were concerned that this might be a ruse by a war party to gain entrance to their camp, but the condition of Mingo, Niargua and their horses convinced them they were harmless.
Mingo told Killbuck and LaBonta that he was a "remnant of a tribe from the Wabash, Tippecanoe and the Kankakee rivers" and told them of this land of plenty along the Kankakee. After refreshed, the two lovers made it safely to the Potawatomi encampment on the Missouri River. Soon afterward Killbuck and LaBonta pulled up stakes and made for the Kankakee Marsh where they hunted and trapped for the rest of their lives.
