A collateral branch of the De Pohers, or Powers, was the Barons of Donoyle, or Dunhill, the ruins of whose castle remain to this day. It was stoutly defended against Cromwell by the Baroness; and, according to tradition, was betrayed into the hands of the enemy by the lieutenant of her garrison. These Powers were then transplanted to Connaught, and their estates were forfeited. Another collateral branch was the Powers of Knockbrit, county Tipperary. In the year 1789, to Edmund Power and his wife, who was a daughter of "Buck" Sheehy, was born Marguerite, who became Lady Blessington. It seems that her father, "Buck" Power, dissipated his fortune, as the mode was in those days; that he compelled his daughter to marry one Captain Farmer, who ill-treated her; that Mrs. Farmer left her husband, came to London with her brother, was painted by Sir Thomas Lawrence, and, after Farmer's death, married Lord Blessington. Here is a link with my Lord Byron. The relation of the De la Poer Beresfords with the Delavals of Seaton-Delaval in Northumberland, consists in the marriage of Sir Henry de la Poer, second Marquess {xxvii} (1772-1826), with Lady Susanna Carpenter, who was the granddaughter of Lord Delaval. Her mother, daughter of Lord Delaval, married George, second Earl of Tyrconnel. The Lady Tyrconnel was famed for her beauty. The portrait of her daughter, Lady Susanna, now at Curraghmore, represents a singularly beautiful, fair-haired creature, delicately featured, blue-eyed. The Delavals would seem to have been a high-spirited, reckless, and spendthrift race. Extravagant entertainments were devised at their house of Seaton-Delaval, which was built by Sir John Vanbrugh, playwright and architect. The actor Foote was a friend of the family; they were devoted to amateur theatricals; and Garrick once lent Drury Lane Theatre to them. The Delavals were singularly addicted to practical jokes; a tendency to the same diversion has reappeared in later generations. Lord Delaval's only son died young, and the title expired. There is a picture of the sturdy, brown-haired lad at Curraghmore. It is worth noting that an ancestor of Lady Susanna, and, therefore, of Lord Charles Beresford, was a naval officer of some distinction. George Delaval, vice-admiral of the Red, was present at the action fought off Cape Barfleur in May 1692.
