He was the eldest of two surviving sons of Edward Sholto Douglas-Pennant, 3rd Baron Penrhyn and Blanche Georgiana FitzRoy, daughter of Charles FitzRoy, 3rd Baron Southampton. He was first commissioned in 1910 and by the outbreak of World War One in 1914 he was aide-de-camp to Baron Carmichael, governor of Bengal. He was killed in action on 29 October 1914 on the Western Front as a lieutenant in 1st Battalion, Grenadier Guards. He was officially reported wounded and missing in November 1914, but on 9 July 1915 the Wolverton Express reported that he had now been unofficially reported killed. He was replaced as heir to the barony by his younger brother Hugh Napier Douglas-Pennant.
