Dudley John Beaumont (1877 – 24 November 1918) was a British Army officer and painter.
He was the first husband of Sibyl Hathaway, 21st Seigneur of Sark, and grandfather of her successor, Michael Beaumont.
[3] Beaumont first joined the British Army as a part-time second lieutenant in the 2nd Volunteer Battalion, Gloucestershire Regiment on 5 August 1905,[4] but he resigned that commission on 24 March 1908.
[5] When the First World War began in 1914, Beaumont joined the 2/5 Battalion Gloucestershire Regiment,[6] By 25 August 1915 he was a temporary lieutenant and was transferred to the General List for service with the West African Frontier Force (WAFF).
There is some contradiction of the official sources in family accounts: in an announcement of his son's marriage in 1924, his rank is given as captain;[11][12] and his wife wrote in relation to his death that in 1918 Beaumont was deployed in France when the Spanish flu pandemic broke out and then had the misfortune of being sent to London on leave at the height of the pandemic in that city.
