Nano Nagle, the foundress of the Presentation Sisters, had the Nagle Coat of Arms.
It has an escutcheon or shield-shaped in heraldry gold denoting generosity and elevation of mind.
In its center is a horizontal bar or fess, which is a military belt or girdle of honor and signifies, that the bearer must always be in readiness to undergo the business of the public weal.
It is azure or blue signifying loyalty and truth.
On the fess are three diamonds in gold.
Above the escutcheon is a nightingale.
The oak design predominates.
It holds the first place among trees and is said to signify antiquity and strength.
Around the escutcheon is a scroll bearing the Nagle motto, NON VOX SED VOTUM, in English, "NOT A VOICE BUT A WISH.", or more freely translated "NOT WORDS BUT DEEDS.""
