Thorn's chief interest was in the acquisition of land. Besides his own empresario contracts with Benjamin R. Milam and Green DeWitt, whereby he obtained a share in each of their grants from the Mexican government, he acquired additional titles to land grants until his holdings amounted to hundreds of thousands of acres. His other business activities included trade with the Indians in the areas of his landholdings, a general store in Nacogdoches operated in partnership with Haden Edwards, a bank, a salt mine, and a lumber business. Thorn also operated large farms both in Texas and in Louisiana and attempted the establishment of towns in East Texas, one of which, called Thornville, was located north of Nacogdoches. His business activities resulted in the accumulation of a fortune estimated at well over a million dollars. He died in Nacogdoches on December 3, 1854, and was buried in Oak Grove Cemetery.
