O'Reilly Genealogy & History
O'Reilly is an Irish surname, an anglicized form of the Gaelic O�Raghailligh, meaning the son of Ragheallach, a given name of uncertain origin and meaning. O�Reilly family history begins in 1237, when Cathal O�Reilly, was recorded as Prince of Breffny in the Records of Lough Oughter Monastery in County Cavan. This suggests that the O�Reilly clan was strong in that region. O�Reilly genealogy includes several interesting people, such as former Chevron Chairman and CEO David O�Reilly and Louisiana colonial governor Alejandro O�Reilly.
