 BIA researchers used records provided by the Hamilton band, records from the Mohegan Church, and records maintained by Gladys Tantaquidgeon, who had kept genealogy and vital statistics of tribal members for her anthropological research.In 1990, the Fowler group, identifying as the "Mohegan Tribe of Indians of Connecticut" (MTIC), decided that the tribe's membership would be restricted to documented descendants from a single family group, ca.1860.
