The first permanent white settler of what is now Atchison county was a Frenchman, Paschal Pensoneau, who, about 1839, married a Kickapoo Indian woman and about 1844 settled on the bank of Stranger creek, near the present site of Potter, where he established a trading-house and opened the first farm in Atchison county on land which had been allotted him by the Government for services in the Black Hawk and Mexican wars. Pensoneau had long lived among the Kickapoo Indians, following them in their migrations from Illinois to Missouri and Kansas, generally pursuing the vocation of trader and interpreter. As early as 1833 or 1834 he was established on the Missouri river at the old Kickapoo town, later removing to Stranger creek, as aforestated. He became a very prominent and influential man among the Kickapoos. He long held the position of Government interpreter that tribe. After the treaty of 1854, diminishing the Kickapoo reserve, Pensoneau moved to the new lands assigned the tribe along the Grasshopper river, where he lived for many years. About 1875 he settled among a band of Kickapoo Indians, near Shawnee, Indian Territory, where he died some years later. He was born at Cahokia, Ill., April 17, 1796, his parents having been among the emigrants from Canada to the early French settlements of Illinois. In 1850 the military road from Ft. Leavenworth to Ft. Laramie was laid out by Colonel Ogden. It crossed Atchison county, and over it passed many important expeditions to the Western plains and mountains, and to Oregon and California. Before this road was laid out as a Government highway, the same route had long been traveled as a trail. It was a great natural highway, being on the “dividing ridge” between the Missouri and Kansas rivers. Charles Augustus Murray, Francis Parkman, Captain Stansbury and other noted travelers journeyed over this trail during the thirties and forties, and in the fascinating volumes they have left, we find much of interest pertaining to the region of which Atchison county is now a part. During the gold excitement in California this old trail swarmed with emigrants seeking a fortune in the West. The Mormons, the soldiers, the overland freighters, the stage drivers, the hundred and one other picturesque types of character in the early West have helped to make the history of this famous old branch of the “Oregon and California Trail” immortalized by Parkman. During the days of Mormon emigration a Mormon settlement sprang up a few miles west of Atchison, and immediately east of the present site of Shannon, which became known as “Mormon Grove.” The settlement was enclosed by trenches, which served as fences to prevent the stock from going astray, and traces of these old ditches may be seen to this day. Many of the Mormons here died of cholera and were buried near the settlement, but all traces of the old burial ground have been obliterated by cultivation of the soil.
