One of the earliest settlers in this area was Mordecai Lincoln, who prior to 1830 led a group from Kentucky in an attempt to establish a Catholic settlement in this part of Illinois, presaging by several years the Mormon settlement in nearby Nauvoo. He was followed by other southerners who were mostly Baptist in faith, including Baptists who had lived close to Mordecai near Springfield, Kentucky. Some of the Baptists settled along Baptist Creek to the northeast of Fountain Green.
The Catholic settlement foundered, in part because of the difficulty in obtaining a parish priest. The Baptist theology was better able to cope with such problems on the frontier.
