Gilbert Sackville, 8th Earl De La Warr

He became heir apparent to the earldom in 1890 when his elder brother, Lionel Charles Cranford, Lord Cantelupe, died without issue in a boating accident on Belfast Lough aged twenty-one.

[1] He served in the First World War but relinquished his commission as a temporary major in The Southdown Battalion of the Royal Sussex Regiment in November 1914.

[13] He later fought in the war as a lieutenant in the Royal Navy Volunteer Reserve and died at Messina, Sicily while on active service on 16 December 1915.

[16] The second Lady De la Warr married secondly John William Dennis, MP for Birmingham Deritend, in 1922.

[1][2] In 1892 a ship named Sunbeam, owned by Viscount Cantelupe, was on a pearl fishing expedition on the northwest coast of Australia.

[17] The story caused some confusion in the newspapers at the time because the Viscount's father-in-law, Thomas Brassey, was the owner of the famous steam yacht Sunbeam RYS and it was incorrectly assumed that this was the ship that sunk.
