Chauncey Hibbard Cooke (May 15, 1846 – May 11, 1919) was a United States Army soldier from Buffalo County, Wisconsin who fought in the American Civil War. After the war ended, he worked as a schoolteacher, teaching former slaves in Texas. Early life and education Cooke was born in Columbus, Ohio in May 1846; he had three brothers and a sister.
