Looking for my gr-gr-grandfather Francis de Courcy O'Grady. Born about 1811. Lived in Natchez, MI in 1840. Married 1849 to Clarissa Barrows of Norwich, Conn. He was a carpenter there till his death. Mother was Hannah of Ireland, age 82 in 1850 census. Brother John G. Grady, b. abt 1808, married Tryphena Barrows. Must be related to O'Grady family of Killballyowen because of middle name. Searching for his birthplace/father.
