The Byrne Coat of Arms is red with a white chevron between three hands.
The chevron represents protection or faithful service. The hand represents a pledge of faith, sincerity and justice. Red signifies a warrior or martyr. White signifies peace and sincerity.
The Crest is a mermaid combing her hair.
The ancient family motto is “Certavi Et Vici” which means “I have fought and conquered”.
