I have found several Tyhurst's that served in the Union Army in the Civil War. Rufus J. Tyhurst (1839-1923) is the brother of my 3rd Great Grandmother Sarah K Tyhurst. Rufus served in the 2nd NE Regiment Home Guards from Missouri and then the 3rd MO Cav. There is a Lorenzo Tyhurst that served with Rufus in the 2nd NE Home Guards (MO). They almost surely were related but I don't know how. There is also a James E. Tyhurst that served in the 12th Kansas Infantry and a William R. Tyhurst that served in the 30th Illinois Inf. Any info. on these soldiers would be appreciated.
