William Starke Rosecrans, a soldier, engineer, and statesman, was born in Delaware County in 1819, grew up in Homer, and graduated from West Point in 1842. During the Civil War, he commanded the federal Army of the Cumberland and, though popular with his troops as "Old Rosy" and victorious at Corinth, Murfreesboro, and Chattanooga, he was a cautious commander who suffered major defeat at Chickamauga in 1863. Before the war he developed coal properties in western (now West) Virginia, and he also helped design St. Joseph's Cathedral in Columbus for his brother Sylvester Horton Rosecrans. After the war he served as minister to Mexico, represented California in Congress from 1881 to 1885, and died in 1898; he is interred at Arlington National Cemetery. Sylvester Horton Rosecrans, born in 1827 one-half mile east of this site, became the first Bishop of the Diocese of Columbus. He attended Kenyon and St. John's colleges, studied for the Roman Catholic priesthood in Cincinnati and Rome, was ordained in 1852, and after returning to Cincinnati officiated at St. Thomas's church and taught in the diocesan seminary, later becoming its president when it became a college in 1859. After the Diocese of Columbus was created in 1868, he became its first bishop, founded St. Aloysius Seminary, established a newspaper, fostered temperance societies, and built St. Joseph's Cathedral, which his brother helped design. He died in 1878, on the day following the dedication of his new cathedral.
