Guy Finch-Hatton, 14th Earl of Winchilsea

Guy Montagu George Finch-Hatton was born on 28 May 1885. He was the son of Henry Finch-Hatton (1852–1927) and the former Anne Jane Codrington.[1] His two siblings were Gladys Margaret Finch-Hatton (who married Capt. Osmond Williams, a son of Sir Osmond Williams, 1st Baronet) and Denys Finch Hatton, a noted big-game hunter.[2]

Finch-Hatton's father was the second son of George Finch-Hatton, 10th Earl of Winchilsea by his third wife Frances Margaretta (née Rice) Finch-Hatton (the eldest daughter of Edward Royd Rice MP of Dane Court). His maternal grandparents were Admiral of the Fleet Sir Henry Codrington and Helen Jane (née Smith) Codrington (a daughter of C. Webb Smith).[3]

He was educated at Eton and Magdalen College, Oxford.[4]

In 1908, he was Lieut with the Royal Engineers. During World War I, he served as Lt Cmdr Royal Naval Reserve from 1915 to 1917 and Lt Col Royal Air Force from 1917 to 1918. He was awarded Distinguished Service Cross and officer of the Order of the British Empire in 1919. From 1922 until his death in 1939, he was treasurer of St George's Hospital.[3] In 1927, Finch-Hatton acceded to the title upon the death of his father, Henry Finch-Hatton, the 13th Earl of Winchilsea.[3]

Shortly after his marriage in 1910, he became a member of the London Stock Exchange and a partner in the firm of Kitcat & Aitken, one of the leading firms of Bishopsgate Street.[4] Lord Winchilsea was also a partner in securities firm of William P. Bonbright & Co. of London and New York.[4] His brother-in-law John Armstrong Drexel was also a partner in the firm.[5]

On 8 June 1910, Viscount Maidstone was married to Margaretta Armstrong Drexel (1885–1952) at St Margaret's, Westminster by the Bishop of London. The reception was held at the Drexel home in Grosvenor Square.[6] Margaretta, who had been presented at court in 1908 by Princess Louise Margaret of Prussia, the Duchess of Connaught, was the daughter of Margarita (née Armstrong) Drexel and Anthony Joseph Drexel Jr., and the granddaughter of Anthony Joseph Drexel, a member of the wealthy Philadelphia banking dynasty.[7] Her parents divorced in 1917 and her mother married Brinsley FitzGerald (the son of Peter FitzGerald, 1st Baronet of Valencia) in 1918.[8] Together, Guy and Margaretta were the parents of three children:
