Lt.-Col. Thomas Peers Williams (27 March 1795 – 8 September 1875) was MP for Great Marlow from 1820 to 1868. He was Father of the House of Commons from December 1867 to 1868. Early life Williams was the son of Owen Williams (1764–1832), MP for Great Marlow, and the former Margaret Hughes (d. 1821), a member of the Hughes family which owned a large interest in the Parys Mountain copper mine. Three of his sister were married to members of the House of Lords, two others to sons of lords. His grandfather Thomas Williams was a prominent attorney and active in the copper industry. His great-grandfather was Owen Williams of Cefn Coch, Llansadwrn, who owned also Tregarnedd and Treffos. Williams' grandfather was retained by the Hughes and Lewis families to act for their in very acrimonious litigation with Sir Nicholas Bayly (father of the earl of Uxbridge) in relation to the Parys Mountain copper mine. When the litigation ended in 1778, Williams' grandfather became an active partner in the mine. Williams matriculated at Christ Church, Oxford in 1813. Career In 1820, he became an MP for the constituency of Great Marlow (usually known as Marlow). The seat had been held by his grandfather from 1790 until his death in 1802 when his own father took up the seat, serving until his death in 1832. Williams retired in 1868 after serving 48 years. In the last year, he was Father of the House of Commons from December 1867, succeeding Henry Cecil Lowther who had entered the House in 1812 and retired as MP in 1867. His eldest son, Owen Lewis Cope Williams, also served as MP for Great Marlow 1880 from 1885, the fourth generation of his family to hold the Great Marlow seat with intervals, from 1790 until 1885, nearly a hundred years. Williams' family gradually released their hold on the copper industry and, today, are chiefly remembered as owners of the Craig-y-don estate, Members of Parliament, and the founders of banks. Estates Williams was a considerable landowner in Wales, as recorded with in 1873. He owned estates in Anglesey and Berkshire, and elsewhere.
