I am descended from William Davis, born in Tennessee about 1826. He appears in the 1880 census in Yell County, Arkansas. His son, my g-grandfather, Andrew Jackson Davis, was born in Arkansas in 1864. Family history is that he was 3/4 Cherokee. I find that a William Davis served in the Civil War in the 1st Cherokee Mounted Rifles. I'm wondering if that might be my g-g grandfather. Does anyone out there know anything about the Cherokee Mounted Rifles or about William Davis?
