Edward Algernon FitzRoy JP DL (24 July 1869 – 3 March 1943) was a British Conservative politician who served as Speaker of the House of Commons from 1928 until his death in 1943.^[2]

FitzRoy was the second son of the 3rd Baron Southampton and his second wife, Ismania Catherine Nugent, a granddaughter of Sir Charles Jenkinson, 10th Baronet. He came from a family with a long line of public service and was a descendant of Charles II's illegitimate son Henry FitzRoy, 1st Duke of Grafton.^[3] Through ancestor Anne Warren, the daughter of Admiral Peter Warren, he was a descendant of the Schuyler family, the Van Cortlandt family, and the Delancey family, all from British North America.^[2][4]

His mother was Lady of the Bedchamber to Queen Victoria and young FitzRoy was a Page of Honour to the Queen.^[2]

A member of Northamptonshire County Council from 1896 to 1921, FitzRoy first entered Parliament in 1900 general election as Member of Parliament (MP) for Northamptonshire South.^[5] He was appointed a deputy lieutenant of Northamptonshire in 1901.^[6] He was re-elected during the January 1910 general election for Northamptonshire South.^[7] He held the seat in the December 1910 general election.^[8]

During World War I, whilst still an MP, he served in the British Army as a captain of the 1st Regiment of Life Guards, was wounded at the First Battle of Ypres and commanded the mounted troops of the Guards Division from 1915–16.^[2]

In the 1918 general election, he was elected for the seat of Daventry.^[9] He held the seat in the 1922,^[10] 1923,^[11] 1924,^[12] 1929,^[13] 1931 and 1935 general elections.^[14]

He served as deputy chairman of the Committee of Ways and Means, briefly during 1923 and from 1924 to 1928. He was made a Privy Councillor in February 1924.^[15] He was elected Speaker of the House of Commons on 20 June 1928.^[16] In 1931, he was awarded a Doctor of Laws degree from the University of Cambridge and an honorary Doctor of Civil Law degree from the University of Oxford in 1934. In 1935, there was considerable controversy when the Labour Party decided to stand a candidate against him in the general election. According to The Times' obituary, "In addition to his former party Mr. Lloyd George and the Liberal leaders came out strongly in defence of his position. Even on the lowest ground of party interest Labour made a grave mistake, for Captain FitzRoy was returned by a resounding majority."^[2]

Fitzroy died in office, aged 73 in Westminster in 1943.^[2] He was succeeded by Douglas Clifton-Brown. In 1983, Labour MP and then Father of the House John Parker paid a humorous tribute to him: "I remember the first Speaker in my time, Captain Fitzroy. He was definitely a bit of a tartar. He disliked new young Members. When he was in the Chair, if someone spoke for too long he banged his hand on the side of his Chair. The longer the Member continued to speak, the more vigorously he hit the Chair. Everyone saw that except, unfortunately, the Member who was speaking, who was not deterred. Captain Fitzroy took a firm revenge and did not call that Member for a long time." Parker also reported, "Captain Fitzroy once told me that, as a descendant of Nell Gwyn and Charles II, the most embarrassing thing that he had had to do in the House was to announce the abdication of Edward VIII. He found that awkward and embarrassing".^[17]

FitzRoy married Muriel Douglas-Pennant on 19 November 1891. She was appointed a CBE in 1918. Upon his death she was given a Viscountcy, the customary retirement honour for Speakers, as Viscountess Daventry.

Fitzroy and Lady Daventry had four children:^[18]

• Robert Oliver Fitzroy, 2nd Viscount Daventry (10 January 1893 – 1986)
• Hon. Nancy Jean Fitzroy BEM (31 May 1894 – 23 November 1983)
• Captain Michael Algernon Fitzroy (27 June 1895  † 15 April 1915)
• Commander Hon. John Maurice FitzRoy Newdegate (20 March 1897 – 7 May 1976), father of Francis FitzRoy Newdegate, 3rd Viscount Daventry

Fitzroy's arms, as displayed in Speaker's House^[19] were the same as those of the Dukes of Grafton.
