Who was the first homesteader?

During the Civil War, the Republican Congress passed the Homestead Act. The act promised ANY settler 160 acres of land if they met the following requirements:

at least 21 years of age, citizens or immigrants who had applied fro citizenship, build a house and live in it at least 6 months each year, and farm the land for 5 consecutive years. After meeting the first to requirements you moved to your new land and worked on the last 3 requirements. If you were a person or a family doing this you were called a Homesteader.
