the century also saw active cultural and genealogical research by James L. Cisco and his daughter Sara Cisco Sullivan from the Grafton homestead, and worked closely with the remnants of other closely related tribes, such as Gladys Tantaquidgeon and the Fielding families of the Mohegan Tribe, Atwood L. Williams of the Pequot, and William L. Wilcox of the Narragansett. Together, various tribal members began sharing cultural memory, with pan-Indianism firmly taking root in the 1920s with Indian gatherings such as the Algonquin Indian Council of New England that met in Providence, Rhode Island and dances or powwows such as those at Hassanamessit in 1924. Plains Indian clothing was often worn as potent statements of Indian identity and to prove their continued residence in the area and because much of the original culture had been lost. Other Nipmuc individuals appeared at town pageants and fairs, including the 1938 appearance at the Sturbridge, Massachusetts bicentennial fair of many ancestors of today's Chaubunagungamaug Nipmuck. By the 1970s, the Nipmuc had made many strides.

Divisions were caused by the frustrations with the slow pace of recognition as well as disagreements about gambling. Land, 190 acres, in the Hassanamessit Woods in Grafton, believed to contain the remains of the praying village were under agreement for development for more than 100 homes. This property has significant cultural importance to the Nipmuc Tribal Nation because it is thought to contain the meetinghouse and the center of the old praying village. However, The Trust for Public Land, the town of Grafton, the Grafton Land Trust, the Nipmuc Nation and the state of Massachusetts intervened. The Trust for Public Land purchased the property and kept it off the market until 2004, after sufficient funding was procured to permanently protect the property. The property also has ecological
