Langdale was born Hon. Charles Stourton in 1787, the fourth son of Charles Stourton, 17th Baron Stourton by his wife Mary Langdale, a daughter and co-heiress of Marmaduke Langdale, 5th Baron Langdale. He became the heir of his mother's cousin Philip Langdale of Houghton Hall, East Riding of Yorkshire, who died with no sons, and to comply with the terms of his inheritance he adopted the surname Langdale by royal licence dated 1815, for himself and his descendants.
Langdale campaigned for Catholic Emancipation, and after the passing of the Catholic Relief Act 1829 he became Member of Parliament for Beverley following the 1832 general election, becoming one of the first Roman Catholics in the House of Commons. He represented Beverly until 1835, and represented Knaresborough between 1837 and 1841. Throughout his life, Langdale took a leading part in all matters relating to the interests of Roman Catholics. He supported the foundation and became the chairman of the Catholic Poor School Committee, serving until his death. During his tenure, he played an important role in the negotiations for public funds for Roman Catholic schools. Shortly before his death, he was admitted as a lay brother of the Society of Jesus. At his funeral, Peter Gallwey described him as "the acknowledged father and patriarch of the oppressed Catholic community in England" and as "a father to us all". Henry Edward Manning, Archbishop of Westminster, in a funeral sermon in London, described him as having been for fifty years the foremost man among the Roman Catholic laity in England.
Biography of Maria Fitzherbert
Langdale had been a close friend of Maria Fitzherbert during their youth; there was a family connection through her first husband George Weld, whose niece married his eldest brother William. In the publication Memoirs of Lord Holland, it was claimed that Fitzherbert, a Roman Catholic, never believed her marriage vows to George, Prince of Wales, to be in any way binding. With a view to the vindication of her character, he published Memoirs of Mrs. Fitzherbert: with an account of her marriage with H.R.H. the Prince of Wales, afterwards King George IV at the request of his brother, Lord Stourton, one of the trustees named in Fitzherbert's will. He was refused access to her papers by the other trustees, but he was able to use the narrative drawn up by Lord Stourton. The memoirs showed that Fitzherbert believed herself to be George's wife.
Secondly in 1821 he married May Constable-Maxwell, eldest daughter of Marmaduke William Haggerstone Constable-Maxwell, by whom he had at least five sons and six daughters.
