Thomas and Sarah Mackey are buried side-by-side in the Le'Qui Court Cemetery in Niobrara. On her headstone, her name is misspelled as Saraha. This is also the way it was spelled on hear death certificate, but not on her probate.
Sarah married to her first husband, Henry Demers, a Frenchman, in Wabasha.
Then I believe when she left him,she went to see her dad in Lincoln County, MN, where she met a farmer named Thomas Mackey, a white man, who lived near Flandreau and married him.
