Jean Henry-Mead, photojournalist, researched and wrote the centennial history of Casper, Wyoming, (where Ennis' married sister lived) titled
Casper Country: Wyoming's Heartland, a centennial edition, which she researched by reading 97-years' worth of microfilmed newspapers dating from 1888.
The book covers the period of prehistory through the mid-1800s emigration period of the Oregon, Mormon and California trails; the Pony Express, Indian wars, homesteaders, outlaws, railroads, political upheaval, gambling, early oil production, Johnson County War, hanging of "Cattle Kate," and historical events through the Sagebrush Rebellion of the 1980s.
