Julia Guerrier

William Bent lost a brother and business partner in the Taos Revolt. Months later, Owl Woman died in childbirth. Bent named the child, a girl, after his late sister Julia. Her Cheyenne name, Um-ah, meant “Talking Woman.” Yellow Woman and Island were still married to Bent, but they disliked the fort. They took over care of William Bent’s children permanently and moved them to Big Timbers.

=========================

On October 14, 1865, the Arapaho and Cheyenne of the Upper Arkansas valley made a treaty with the US government. US representatives included Bent and Kit Carson, who was Special Commissioner. The US apologized to the Arapaho and Cheyenne for the Sand Creek Massacre. Some of the tribe members did not approve of the treaty, which would limit them to a reservation south of the Arkansas River, rather than their traditional territory to the north, which was larger.[79]

As part of the treaty, four of Bent's children, as Cheyenne, were each awarded 640 acres land on a reservation south of the Arkansas River, between Red Creek and Buffalo Creek:[80]

Mary Bent Moore and her three children: Adia Moore, William Bent Moore and George Moore George Bent Charles Bent (He was later killed by US Indian scouts; in 1869 most of the Dog Soldiers band was killed during the Battle of Summit Springs by Pawnee scouts and US forces.) Julia Bent Robert Bent was awarded 640 acres in Sulphur Springs, north of the Arkansas River.[81]

William Bent assisted in the negotiation of the treaty with the Kiowa and Comanche on October 18, 1865.[82]
