James W. Bosler came to Wyoming in the late 1860s and worked as a beef contractor, dealing with the United States Army and with Indian agencies in Wyoming, Colorado and New Mexico. Bosler's son, Frank C. (1870-1918) continued in the cattle business in Wyoming, establishing extensive ranching operations and gaining vast interests in mining operations and irrigation and hydroelectric plants. Frank resided at times in Carlisle, Pennsylvania, and in Albany County near Rock River and McFadden, Wyoming, where most of his businesses were headquartered.
Frank Bosler was owner of the Iron Mountain Ranch Company, Diamond Ranch and Ione Ranch, and general manager of Diamond Cattle Company, Rock Creek Conservation Company (an irrigation company responsible for the development of farming in Rock River), and Iron Mountain Alloy Company (an ore treatment company). His cousin, Abram Bosler was largely involved in his businesses. At Frank's death, his wife Hannah Elizabeth (1882-1944) and son Frank Jr. (1916-1993) continued ranch operations in Albany County.
