Family connection to the Sioux Uprising

A marker erected in Kandiyohi, Minnesota commemorating the spot of the Sioux Uprising in 1862 and the people that died. Most of those killed on this spot were relatives of mine. It was erected by the lone surviving family member in 1917. He is the oldest son mentioned below. The following is a brief history of some of those that died:
