The question is, who is John Arnett? Since John Arnett was listed as an intruder in the Cherokee Nation in 1886, he could have been the father of Annie and Alma? In trying to analyze this, I offer these thoughts and the footnote(1) of Chapter III
John has not shown up in any other Oklahoma list or record. If he died before 1900, he would not show up in the census report. Nor could he have applied for a Civil War pension in Oklahoma when it was possible in 1912.
I also found a record John Arnett (born June 20, 1760 of North Carolina) He enlisted from Anson Co. NC. He received a pension for fighting in the Revolutionary War, May 6, 1833. at that time he lived in Decatur County Georgia. He had a brother also a resident of Chesterfield, SC (Next to Anson Co.). that was 38 and lived in Shreven, County GA.. in 1833. It is possible this could have been the (Oklahoma) John Arnett's father or grandfather.
Whatever his first name, originally I thought the Arnett we are looking for might have fought for the Confederacy. A war record or pension application filed in Georgia, Texas or Arkansas might tell where he was born, who his father was etc. (When I was in Georgia, I only looked for Lee Arnett) and did not find anyone with that name. A military record might show a John, but John and Arnett are very common names in the south, so that still might not prove the connection with Annie and Alma. Nothing has been found to prove a connection to Annie or Alma. See footnotes at the end of this chapter for searches that have explored other directions.
The Intruders list indicates John Arnett did not arrive on his Cherokee land until 1886 and his (son?) Lee until 1890. Maybe the Railroad job gave out after the Railroads connected at El Paso in 1881. After that, John wanted to settle down. He had passed through the Porum area while working on the Katy, and knew people there, and became a squatter in the Cherokee Indian Nation.
