I have a copy of the 1881 History of Fremont County, Iowa, and on pages 526-27, it describes this incident of the killing of W. M. "Miniature" Holloway, January 14, 1869. It states that "William Jackson and James Orton, both young men and then residing in the neighborhood, came to the house. They were regarded as rough characters and were not invited in." They later came back drunk and during a fight, the killing took place by "cutting Holloway's throat." A nephew of Mr. Holloway shot Jackson, who escaped into Nebraska, but he was arrested the next morning. The two charged with the murder were later taken from the jail by a gang of men and hanged. "The bodies were taken in charge by relatives and buried. Jackson's mother resided on the Missouri (River) bottom. Orton had a brother, a very excellent man, living near Bartlett." If Jackson's mother lived near town but on the Missouri river bottoms, I would think she would be in the 1870 census probably.
