Rory was born into a family of sculptors, said to have originated in Callan, County Kilkenny. According to his own signature in Kilcooly Abbey, his father's name was Patrick.^[1] Rory was primarily a sculptor of tombs, some of which he signed. Among his more prominent works are three tombs in Kilcooly Abbey, the resting place of Sir John Grace and his wife, Honora Brenach, at Grace's Chapel, Tullaroan, County Kilkenny, and the tombs of Robert Walsh and his wife, Katherine Poer, at Jerpoint Abbey. He also carved the Trinity Stone once housed in St. Mary's Church, Callan,^[2] now in the Catholic Church in Callan.
