While doing some online research today, I ran across an interesting article in the Holt County (Mo) Sentinel, May 21, 1915, entitled "They Went to the Front": The Muster Roll of Company "F", Fourth Missouri State Militia Cavalry. PP. 1 & 8.

The article provides a history of the company, a muster roll, and photos of the regimental colonel and the company officers, all in uniform.
