In 1848, the Massachusetts Senate Joint Committee on Claims called for a report on the condition of several tribes that received aid from the Commonwealth. Three reports were listed: The 1848 'Denney Report' presented to the Senate the same year; the 1849 'Briggs Report', written by Commissioners F. W. Bird, Whiting Griswold and Cyrus Weekes and presented to Governor George N. Briggs; and the 1859 'Earle Report', written by Commissioner John Milton Earle that was submitted in 1861. Each report was more informative and thorough than the previous one. The Nipmuc require having an ancestor listed on these reports and the disbursement lists of funds from Nipmuc land sales. The lists did not count all Native Americans, as many Native Americans may have been well-integrated into other racial communities and due to the constant movement of Native Americans from place to place.
