 In April 1784 , the Rowans and five other families set out for a tract of land on the Long Falls of the Green River that Rowan had purchased before leaving Pennsylvania . The party arrived on May 11 , 1784 , and constructed a fort which they dubbed Fort Vienna . The fort , then located approximately 100 miles from the nearest white settlement , is the present @-@ day town of Calhoun . The settlers at Fort Vienna frequently clashed with the Shawnee who used the area as a hunting ground . The Rowans would remain at Fort Vienna for six years .
