The Millan family coat of arms features a silver shield with a red bend dexter and a blue chief. The red bend is charged with three silver mullets, while the blue chief is charged with a gold bezant. The crest of the coat of arms is a demi-lion rampant issuant from a gold coronet, holding in its dexter paw a red sword, and in its sinister paw, a bundle of three silver arrows. The motto of the coat of arms is "Fortiter et Fideliter," which means "With Strength and Fidelity."
