Civil War soldier Perrine Carson (1821-1866) was the brother of my ancestor, Caroline Carson (ca. 1829/30-1915). He was injured in service when building a bridge, and died within a year of his honorable discharge from the Army. His widow, Sarah Ann Carson, died in 1867, leaving five children under the age of 16.
