Seeking date of death and burial site of Sumner F. Keyes. Living in Madrid, Nebraska, on 1890 census. Reported to be buried in Madrid, Nebraska. Served in the 4th Vermont Vol. during the Civil War and survived Andersonville.

David, looked into your query, attempting to trace Sumner Keyes and do not find burial information. The 1890 Veterans census, states Elizabeth R. Purdy as Widow of Sumner Keyes. He is most likely interred in the Madrid cemetery. Elizabeth moves on to CO, at times living with her son, and also sister, or possibly sister in law.
I was unable to find Sumner on the 1870 census. He may have been an inpatient, due to his time at Andersonville. On the 1890, he states disabilities caused by the war and being a POW. Hope someone local can help you out. Jean
