Onangwatgo is the Oneida name of the notable chief and priest Cornelius Hill (1834-1907). The name derives from the Oneida language, meaning "big medicine," composed of the word onúhkwaht ("medicine") and the suffix -koó ("big, great").Historical and Cultural SignificanceOnangwatgo was a hereditary chief of the Oneida Nation, one of the five founding tribes of the Iroquois Confederacy. The Oneida had allied with the Americans during the Revolutionary War but later faced pressure from white settlers. Many Oneida relocated to Wisconsin in the early 1820s, where they encountered Christian missionaries, particularly from the Episcopal and Methodist Churches. Cornelius Hill, a lifelong Episcopalian, was ordained as a priest in the Episcopal Church at age 69 and ministered to his people, fighting to preserve tribal lands and treaty rights until his death in 1907. His name Onangwatgo reflects his tribal status and perceived prowess—likely both in spiritual and political affairs as a leader and medicine person.Notable BearersThe primary notable bearer is Cornelius Hill (1834-1907), the last hereditary chief of the Oneida Nation, known for his diplomatic efforts against U.S. encroachment and his role as an Episcopal priest.Related Names and FormsOnangwatgo has no widely attested variants in English but is linked etymologically to Oneida root elements found in other Native American names.Key FactsMeaning: Big medicineOrigin: Oneida (Iroquoian language family)Type: First name, traditional chief/leader nameUsage Region: Indigenous North America, specifically Oneida Nation
