In 1799 the famous American pioneer Daniel Boone (1734-1820) moved to what is now St. Charles County, Missouri, where he lived about 50 miles up the Missouri River from St. Louis, Missouri, where the expedition started and finished. "In 1804 Meriwether Lewis and William Clark visited Boone before embarking on their expedition, gathering valuable information about the lands to the west, which Boone had not been able to resist exploring." The Lewis and Clark Expedition passed near Boone's residence on the way up the Missouri River in 1804 and again on the way down the river in 1806. When Shields returned from the expedition to the Oregon Coast he hunted and trapped in Missouri with Daniel Boone. Shields later moved to Harrison County, Indiana, where he hunted and trapped with Squire Boone, a brother of Daniel Boone. Some historians show that John Shields was a "kinsman" of Daniel Boone, but there does not appear to be any evidence they were related.
