John Small had a gunsmith son, William M. Small, born in Vincennes in 1797, who was working on the Illinois side of the Wabash by 1821. John Small had built a mill there, in what is now Lawrence County, Illinois, in 1807 or 1808. William M. Small's first shop was at Small's Mill, on the Embarass River, about a half mile above the Wabash. He later moved into Lawrenceville, which began to flourish during the 1820's. I have never seen a rifle made by William M. Small, but sure would like to. He was still in business as a gunsmith at the time of his death, on August 4, 1876.
An ad, from the STAR SPANGLED BANNER, Lawrenceville, Illinois, June 11, 1847. reads as follows:
