1905 Payroll, 1899-1905 St. Paul City Directory and Census. Andrew Knutson was born in Sweden in 1854 and emigrated in 1872. He worked on the Capitol as a laborer in 1899, is in the 1905 Payroll records, and got on as a janitor when the construction was completed. He was still a janitor there in 1920.

Most of the workers who constructed the Minnesota Capitol belonged to unions. However, it is not clear whether St. Paul laborers were organized during the period when the Capitol was built nor how many laborers or which jobs were represented by a union between 1896 and 1907. So Knutson's union status is currently unknown.
