From here:
Not unworthy of record among these devoted servants of Christ is the name of the Rev. Cornelius Hill. He was the oldest and last of the Oneida Chiefs and from an early age had taken his seat in the Indian Councils. He bore the name of Chief Onon-Gwat-Ga, or Great Medicine, and was one of the most influential in the tribe. He became converted to Christianity, studied at one time at Nashotah, was the interpreter in the Church for many years until the day of his death; was ordained to the diaconate and priesthood by myself; at one time was sent to the General Convention from this Diocese and was ever a most earnest and devoted and faithful Christian and Churchman.
It is owing, in no small measure, to his example and teaching that the tribe has so progressed in temporal civilization and in its spiritual life. There is, as it is well known, no remaining party of heathen on the reservation. The Indians are for the most part loyal and devoted children of the Church.
By their zeal and devotion they are, in many ways, an example to us white Americans. I cannot speak of Father Hill’s loving loyalty to myself without much feeling. His name will ever be cherished amongst his people and held in high regard in our Diocese.
