There were large amounts of first generation immigrants from England and Germany living in Big Horn County when World War I broke out in Europe.

The two groups went out of their way to maintain cordial relations with one another, and the county did not see the sorts of anti-German sentiment that was common throughout much of the country.

While the English residents were outspokenly pro-British, and many of their Wyoming-born sons went to Canada and joined the Canadian Armed Forces in order to serve in the war on England's side, they nonetheless made sure that their German co-workers and neighbors were not harassed or discriminated against.

In late 1917 one English rancher referred to the effort as making sure that his German neighbor was always "treated like a gentleman."

Another English rancher said that two of his ranch hands were from Germany and he "would hate to see the foolishness of national hatreds inflicted on men as decent as they are."

German immigrants and their Wyoming-born children were not "anti-British" though they favored America remaining neutral in the conflict.

Before the war the most commonly read works of fiction among German-born residents of Big Horn County were German language translations of British adventure stories including The Four Feathers by A. E. W. Mason as well as Sherlock Holmes stories and The Light That Failed by Rudyard Kipling.

The others are Sabine (Texas and Louisiana), Union (Arkansas and Louisiana), Bristol (Massachusetts and Rhode Island), Kent (Maryland and Delaware), Escambia (Alabama and Florida), Pike (Illinois and Missouri), Teton (Idaho and Wyoming), Park (Montana and Wyoming), and San Juan (New Mexico and Utah - albeit through a single point, the four corners).
