Baron Harlech, of Harlech in the County of Merioneth, is a title in the Peerage of the United Kingdom. It was created in 1876 for the Conservative politician John Ormsby-Gore, with remainder to his younger brother William. He had previously represented Carnarvon and North Shropshire in the House of Commons. Ormsby-Gore was the eldest son of William Ormsby-Gore, Member of Parliament for County Leitrim, Carnarvon and North Shropshire, and the great-great-great-grandson of William Gore, third and youngest son of Sir Arthur Gore, 1st Baronet, of Newtown, second son of Sir Paul Gore, 1st Baronet, of Magharabag, whose eldest son Paul was the grandfather of Arthur Gore, 1st Earl of Arran.
Lord Harlech was succeeded according to the special remainder by his brother William, the second Baron. He was a former Conservative Member of Parliament for County Sligo and County Leitrim and also served as Lord Lieutenant of County Leitrim for many years. His son, the third Baron, represented Oswestry in the House of Commons as a Conservative and served as Lord Lieutenant of County Leitrim and of Merionethshire. He was succeeded by his son, the fourth Baron. He was a Conservative politician and notably served as Postmaster-General, as First Commissioner of Works and as Secretary of State for the Colonies. His second but eldest surviving son, the fifth Baron, was a prominent Conservative politician and diplomat. From 1961 to 1965 he served as British Ambassador to the United States. As of 2016[update] the title is held by his grandson, the seventh Baron, who succeeded in 2016. As a descendant of both Sir Arthur Gore, 1st Baronet, of Newtown, and Sir Paul Gore, 1st Baronet, of Magharabag, he is also in remainder to these titles.
HTV, now known as ITV Wales, is an independent television company established by David Ormsby-Gore, 5th Baron Harlech, and the company was initially known as Harlech Television until 1970. The "H" in HTV stands for Harlech.
The family seat is Glyn Cywarch, near Talsarnau, Gwynedd, Wales. The former family seat is Brogyntyn Hall, near Oswestry, Shropshire. The 7th Baron sold off almost £2.6m in family heirlooms to fund restoration of Glyn Cywarch.
