John M. Weidemeyer was born January 10, 1834, in Charlottesville, Virginia. By 1850, John and his parents moved to Osceola, St. Clair County, Missouri. Weidemeyer married Lelia V. Crutchfield in 1856, and the couple resided in Osceola until the outbreak of the Civil War in 1861. Weidemeyer and his family supported the Confederacy and Missouri’s secession from the Union. Weidemeyer recorded in his diary and letters to his wife, Lelia, the struggles of military life for a Confederate soldier. He also gave a first-hand account of the raid and burning of Osceola by James H. Lane and Charles Jennison’s Jayhawkers. John M. Weidemeyer was Captain of Company F of the 6th Missouri Infantry CSA and served in Missouri, Arkansas, but the regiment primarily assisted the Confederate Army on the East coast. After the war, Weidemeyer rejoined his family in Texas, before moving them to Clinton, Missouri, where they lived the remainder of his life. John M. Weidemeyer died on January 12, 1911, at 77 years old.
