As I understand it... Watie lived on the west side of the river. He died on the east side of the river and the water was too high to get him home so he was buried at the Polson Cemetery. Sarah Caroline Bell Watie was buried on the west side at O'field Bend but later moved to Polson Cemetery.
The Waties apparently had property including houses at two or more locations. He had the house of the west side of the Grand on or near the Ft Scott-Ft Gibson Military Road (aka the Texas Road or Emigrants' Road) and next to his bro-in-law James Madison Bell. The Waties and Bells moved there sometime before the war and lived there until their deaths. Watie apparently had a house near Honey Creek and near the Polson Cemetery. He had a mill at which he may have had a house on Spavinaw Creek near the mouth of Brush Creek. Seems local lore says he had another house near Honey Creek south or south east of Grove, as I remember.
I'm curious as well about the O'fields in Watie's Regiment. The O'fields apparently lived very close to the Waties and Bells. Though there were Pins in the area too, there were many "Southern" Cherokee from where Watie lived to the Missouri line including the prominent Fields, Thompson, and Parks families. Not everyone was pleased with Ross's handling of the removals and particularly the scandal about where all the money went. While "generally" the full bloods aligned with Ross and generally the mixed bloods aligned with Watie, obviously there were exceptions. In addition, since Watie's home was there, the Confederate Cherokee were often camped in the vicinity at the beginning of the war.
Depending on their English education and their connections to the Watie faction, they may have known things about Ross that were not common knowledge among the full bloods besides being influenced by the Southern Cherokee point of view.
