Starting in the late 1820s, settlers of English, Scottish, German, Welsh, and Scots-Irish ancestry began moving into the area. The first of these settlers was Lunsford Oliver, who arrived from Tennessee in 1829 and located near Shoal Creek, giving his name to Oliver's Prairie. His nearest neighbors were in Springfield, sixty miles to the east. In 1831 he was joined by Nathaniel Turner, John Smith, Joseph Ross, Campbell Pure, Blake Wilson, Levi Lee, Carmac Ratcliffe, and George McInturf. McInturf built a corn mill, the first mill of any kind in the region. Soon afterward came Mathew H. Ritchie, who founded the town of Newtonia near Oliver's Prairie, and John W. McCord, who settled near Walbridge Spring with Levie Lee and founded the town Neosho to the west. In these years the region was called "Six Bulls", a colloquialization of "six boils", referring to the large streams that flowed through the area - Shoal Creek, Center Creek, Indian Creek, Spring River and North Fork.
