Great Grandmother

I would love to know my great grandmother and great grandfathers names, my grandmother died when my mom was 12 years old and if she ever told mom she was to young to remember. Her name Is Sarah Young Kee (Key)Born around 1871 in Tenn. she married William Joesph Kee (Key) Born 1859 maybe in Henry County Tenn.. He lived with the Cherokee. I know they had 3 boys Charles Essig, William Alford, John Allen, 1 girl Nettie May Kee born in Big Lake, Township Miss County Arkansas. Her Father was suppose to be a cheif, is what my mother was told. I have looked but keep hitting dead ends on this. Thank you
