The De la Poer, Power, or Poher, family traces its descent from Comorre I., Count of le Poher, who married the widow of Jonas, King of Domnonée, and who died A.D. 554. Le Poher was one of the five independent states of Brittany, of which the others were La Domnonée, La Cornouailles, Le Vannes, and Le Leon. The genealogy of the Le Poers is {xxiv} interesting, if only by reason of its romantic names. From Comorre I., Count of le Poher, descended the Counts Comorre, Erispoë, Rivallon, Nominoë. Nominoë married one Argantal, defeated Charles the Bald, drove the Franks out of Brittany, and was proclaimed King of that country in 841. He was succeeded by his son Erispoë, who married Mormohec. From the aforesaid Rivallon descended Salomon, who (having achieved a little murderous intrigue) succeeded King Erispoë, and married Wembrit. From the brother of Salomon, Mathuedoi, descended Alain, Count of Vannes and Duke of Brittany, who fought against the Normans, and who was driven by them to take refuge in England. His son Alain (called Barbe-torte) returned to Brittany, drove out the Normans in his turn, and united Le Poer to the Duchy. From the Pohers, in the female line, descended Arthur, Duke of Brittany, who was done to death by John, King of England, A.D. 1203. There is this other link between John of England and the De la Poers, that in the demesne of Curraghmore an ancient bridge of stone, over which the English King is said to have passed, spans the river and is called John's Bridge to this day. From the Duchess Constance, the mother of Arthur of Brittany, descended the Duchess Anne, who married King Louis XII. of France. Brittany was thus incorporated in France. The Pohers seem to have come to England with Duke William of Normandy, called the Conqueror. In 1066 they are found in Devonshire; and later, in Leicestershire, Northamptonshire, Shropshire, Warwickshire, Gloucestershire, Wiltshire, Herefordshire; a fructuous and an acquisitive clan. They came to Ireland in the reign of the second Henry: then came Sir Robert, Sir Roger, William and Simon. Sir Roger helped in the invasion of Ulster. But the founder of the De la Poers of Curraghmore was Sir Robert, who, in the year 1172, accompanied King Henry II. as Knight Marshal, and to whom was given by the King, the town of Waterford and a great parcel of county Waterford. {xxv}
