Ancestry.com has added another 3.2 million Indian historical documents to its database.

The American Indian Documents come from the Oklahoma Historical Society and deal primarily with the Five Civilized Tribes -- the Cherokee, Chickasaw, Choctaw, Muscogee Creek and Seminole nations. They include Dawes roll records, Census documents from Oklahoma and Indian Territory and allotment sales from the state.

“This will be the most comprehensive collection of Indian records," Lisa Arnold, senior content strategist at Ancestry.com, told the Associated Press. The site now boasts more than 10 million Indian records, according to Facebook.

The release of the records comes in conjunction with Ancestry Day in Oklahoma on November 7-8.
