Here is a write-up on the John German Family (link to article below). If you email me directly, I have a picture of the headstone that I can send you.
One day's journey east of Fort Wallace, the John German family, consisting of his wife and seven children, prepared to continue on their way west when they were attacked by a band of Cheyenne. Only the four youngest, all girls, were spared. After having just witnessed the brutal murders of their family, the four young children, Sophia, Catherine, Julia, and Adelaide were allowed to live. All four girls were taken captive by the Cheyenne. Due to the hard winter, however, the Cheyenne did not keep all the girls for long, and the two youngest, Julia and Adelaide (aged 7 and 5) were left on the prairie in what is now the Texas panhandle. They survived on their own for 6 weeks until they were finally found by soldiers. They were 7 and 5 years old respectively. Sophia and Catherine continued traveling with the Cheyenne, although they were eventually split up and traveled with different parties. Meanwhile, soldiers at Fort Wallace received word of the massacre and began the search for the remaining members of the German family, as well as negotiations with the Indians. On February 26, 1875, largely due to efforts made by soldiers stationed at Fort Wallace and elsewhere, the Cheyennes released Catherine and Sophia German at an Indian reservation. The two girls then traveled to Fort Leavenworth where they were reunited with their sisters Julia and Adelaide.
