Independence was founded by pioneers who migrated from Independence, Missouri. Elvin A. Thorp arrived in the Independence area in 1845 and staked a claim north of Ash Creek in June of that year. He platted a small townsite that later became known as "Thorp's Town of Independence" or the "Original Town of Independence", now known as "Old Town". It was named by Mrs. Thomas Burbank, wife of one of the earliest pioneers, who settled 2 miles (3.2 km) south of the city.
