Coppinger came from one of the most prominent families in Cork city; though himself of Hiberno-Norse rather than Old English or Gaelic descent, he was hostile to the English settlement of Cork, and had a reputation for ruthlessness.

The Court of Castle Chamber was a Irish court of special jurisdiction which operated in the sixteenth and seventeenth centuries.
