The le Poer family claims descent from Sir Robert De Poer, who came to Ireland with
Strongbow in 1172.
King Henry II of England, who, by charter, granted to Robert the
City of Waterford, with "the whole province thereabouts;" and made him marshal of Ireland. Edmund, 1st
Count de la Poer, 18th Lord le Poer and Curraghmore (1841–1915), who commissioned the building of Castle Gurteen de la Poer in 1863, was created 1st Count de la Poer (
Papal States) in 1864. The Count was High Sheriff of County Waterford in 1879; Private Chamberlain to Pope Pius IX; HM Lord-Lieutenant for the county and city of Waterford, 1909. His second son, John William Rivallon,
JP, 19th Baron and 2nd Count (1882–1939), was High Sheriff of County Waterford in 1913. In 1922 he claimed the barony of Le Poer and Curraghmore, and Committee of Privileges of the
House of Lords decided that but for the attainder of John Power in 1691, the claim had been established. His eldest son, Edmond Robert Arnold, 20th Baron and 3rd Count, succeeded to the title of 20th Baron le Power and Curraghmore in 1939. He sold Castle Gurteen in 1979 to German businessman Günter Rombelsheim, but retained the right to live in the West Wing of the castle. He died on 20 November 1995 at age the age of 84. ==Gottfried Helnwein==
