Caleb and Nancy Magill with their six children were part of a wagon train traveling fro Brown County, Kansas, to Dallas, Oregon, in 1864. After leaving Fort Laramie their three-year-old daughter Ada was taken sick with dysentery. At Deer Creek Station she worsened. An hour before dawn on July 3, 1864, Ada died. In "Sunday best tiny calico dress" she was buried on a small rise of ground just south of here.
In 1912 a new highway under construction was to have passed directly over Ada's grave. Her remains were moved thirty feet north to this spot. Wyoming's state engineer, Loren Clark Bishop, fashioned the headstone which now marks the final resting place of this pioneer child.
The Oregon Trail is about fifty feet south of this spot.
