According to a tradition current among some of my cousins, my great great grandmother Rachel (Roberson) Horne (1847-1944) was Pawnee. I don’t think so. Nothing else points in that direction.
I asked my grandmother Evelyn (Horn) Miller one year at Powwow about our Indian ancestry. She said she had always assumed they were Pawnee. A few years later she told her daughter Fern she had lately changed her mind. She now believed they were Cherokee because they owned slaves, which is something the Cherokees did.
I think the idea Rachel was Pawnee was probably just an assumption based on geography. Rachel’s parents lived in Atchison County, Missouri, just across the Missouri River from the Nemaha Half Breed Reservation (established 1830, dissolved 1860), as well as from land ceded by the Pawnee in 1833. Rachel’s family settled in this area in 1839.
