I am looking for someway or someone who might have knowledge of Dellie Campbell working at a ranch in the early 1900's along the Powder River. It hasnt been proven that he worked there, but he would be gone for a few months at a time, and come home with money. It was rumored by some that he traveled from MO to the west and worked at one particular or even many different ranches. There is a picture of Dellie standing in chaps on a ranch. But it is unknown where. Does anyone know how to research this? Thanks alot.
