Duke of Leinster - Coat of Arms

Coat of Arms

The coat of arms of the Dukes of Leinster derives from the legend that John FitzGerald, 1st Earl of Kildare, as a baby in Woodstock Castle, was trapped in a fire when a pet monkey rescued him. The FitzGeralds then adopted a monkey as their crest (and later supporters) and occasionally use the additional motto Non immemor beneficii (Not forgetful of a helping hand). The motto "Crom A Boo" comes from the medieval Croom Castle and "Abu", meaning "up" in Irish; Crom Abu was the FitzGeralds' medieval warcry. Crom (Croom) and Shanet (Shanid) were two castles about 16 miles apart in Co Limerick, one being the seat of the Geraldines of Kildare, and the other that of the Geraldines of Desmond, whose distinctive war cries were accordingly “Crom-a-boo” and “Shanet-a-boo.” In 1495 an act of Parliament was passed (10 Hen. VII. C. 20) “to abolish the words Crom-a-boo and Butler-a-boo.” The word “Abu” or “Aboo,” an exclamation of defiance, was the usual termination of the war cries in Ireland, as in a' buaidh, "to victory!"
