Work in progress - In mom’s 1975 Christmas Card, it states, “had a letter from Ellen Freese in Denver telling of the death of her father W.H. Cunningham. Uncle Cunny who was well into his nineties is the last of Lena’s cousins -- the Oklahoma Shepherds with whom she stayed while giving piano lessons to younsters -- most of them Indians.”10

A possible answer to the Saults / Cunningham relation is - William H. Cunningham was the son of Jesse Cunningham and the grandson of Joseph. Joseph can be found on the 1850 census in Pettis County, Missouri. William was married to Grace Shepherd, who’s mother was a Graham. Alice B. Graham was Daniel Napoleon Salts first wife. But I honestly can’t find the link. I really do think it has something to do with the Wells and Ray families in the same area.
