[citation needed] They remained in Ohio only a short time before moving to the Indiana Territory, accompanied by John's two brothers (Samuel and James) and their families.
They lived initially at the fort at Connersville because of trouble with the Indians, but John was the first man to leave the protection of the defense to look for permanent settlement.
In 1816, he settled nearly 100 acres (0.40 km2) along a canyon by waterfalls in what later became Owen County, in the area of what is now McCormick's Creek State Park.
John Jr. also built a tavern where a meeting was held in June 1820 to decide the location of the capital of the new state of Indiana.
The site of the John McCormick, Jr. log cabin is today marked with a boulder and plaque in White River State Park, and a student residence at nearby Indiana University Purdue University Indianapolis (IUPUI) is named for him.
