Sir Charles Welby, 5th Baronet

Sir Charles Glynne Earle Welby, 5th Baronet, (11 August 1865 – 19 March 1938) was a British civil servant who became a Conservative Party politician. He sat in the House of Commons from 1900 to 1906, and then had a long career in local government in Lincolnshire.

Early life Welby was the second son of the Conservative Party politician Sir William Welby-Gregory, 4th Baronet and his wife Victoria, a philosopher of language who was the daughter of Charles Stuart-Wortley. He was educated at Eton College and then at Christ Church, Oxford. When the Conservatives resumed office in 1895 he became private secretary to the new War Secretary Lord Lansdowne, holding the post until 1899 or 1900

After resigning as private secretary in 1899, he was elected at a by-election in February 1900 as the Member of Parliament (MP) for the Newark division of Nottinghamshire,

He was re-elected unopposed at the 1900 general election. In November 1900, he was appointed an extra (unpaid) Assistant Under-Secretary of State for War to assist during the pressure of the Second Boer War. He resigned the appointment in August 1902, two months after the end of the war and following the reshuffle of the cabinet.

Maria died in 1920. Her father Lord Augustus Hervey had been the second son of the 2nd Marquess of Bristol. When his older brother, the 3rd Marquess died in August 1907, he would have succeeded to the title had he not died in 1875. On 15 November the King decreed that the children of Lord Augustus would "enjoy the title, rank, place and precedence as the sons and daughters of a Marquess", which they would have held if their father had survived.

Welby died at a nursing home in London on 19 March 1938, aged 72. He was succeeded in the baronetcy by his second son, Oliver Charles Earle Welby (1902–1977).
