I am new at this and hope someone can help me to find more info. on a grandfather named Henry William French, a private in Capt. Rufus M. Hooker's Company of the 8th Regiment of Cavalry volunteers of the State of Illinois. He joined at Woodstock, Ill. and was mustered in at St. Charles, Ill on Sept. 18, 1861. He was discharged in 1862 due to severe rheumatism. He later married but I don't have a name and they had three children, Will, Frank and Lucy. Can anyone help me? They lived in the Bolckow, Mo. area.
