John Evans

Mapping the way

By Joseph A. MussulmanKristopher K. Townsend

John Thomas Evans (1770–1799), was a Welsh explorer in search of the mythic Welsh, or Madoc, Indians said to be residing in North America. The London literary society, the Gyneddigion, sponsored Evans to sail to America and find the lost tribe established by Prince Madoc—their “Lost Brothers in America.”[1]W. Raymond Wood, Prologue to Lewis & Clark: The Mackay and Evans Expedition (Norman: University of Oklahoma Press, 2003), 43,97.

By 1795, Evans was in the employ of Scotsman James Mackay. Both were from St. Louis, both were naturalized Spanish citizens, and both had been hired by the Spanish government to represent Spain’s right to displace British trading companies and maintain control of commerce in Upper Louisiana.

John Evans proceeded up the Missouri River under Mackay’s orders to explore all the way to the Pacific Ocean. He got no farther than the Mandan and Hidatsa villages at the Knife River, but there he queried his Indian hosts about Western geography and learned of a waterfall “of an astonishing height” about six hundred miles to the west of the Mandans, the Great Falls of the Missouri. He subsequently provided Mackay with six detailed maps of the river from Fort Charles to the Knife River, and a seventh from the Knife River to the Rockies based on Indian information he had gathered. It is certain the captains had his seven maps, the most significant outcome of the Mackay-Evans Expedition.

The Mythic Madoc Indians continues to thrive in popular culture, bringing renewed interest in John Evans’ history. On his return to St. Louis, he renounces the entire idea of the there being Welsh Indians:

[15 July 1797]

Dear Sir,

. . . . .

Thus having explored and charted the Missurie for 1800 miles and by my Communications with the Inians this side of the Pacific Ocean from 35 to 49 Degrees of Latitude, I am able to inform you that there is no such People as the Welsh Indians, and you will be so kind as to satisfie my friends as to that doubtfull Question.

I am, Dear Sir, with due respect, your very humble servant, J. Thomas Evans.[2]John Evans to Samuel Jones, Papers of Dr. Samuel Jones, Pennepek Baptist Church, Lower Dublin Township, Mrs. Irving H. McKesson Collection of Pennsylvania, Philadelphia; reprinted from Williams, … Continue reading

Of course, those seeking to turn myths into historical evidence will only think the Dr. Jones letter is a fake. More rightfully, John Evans should be remembered for his significant contributions to the Lewis and Clark Expedition.
