Hubert was born on 24 September 1894, the younger brother of Arthur Jessie Briars. He was at LWGS for seven terms as a Foundation Exhibitioner from September 1907 to December 1909, placed on entry in form III, and leaving from form V. On leaving school he became a clerk to Mr F E Burrows, an Auctioneer and Estate Agent in Thame. He enlisted as a territorial soldier for four years’ service in the 4thBattalion of the Ox and Bucks Light Infantry in 1912. The attesting officer was (Dr.) John Orlando Summerhayes, LWGS school doctor and in command of the Thame Territorial unit, which was mobilised at the start of the war and sent to France in April 1915. Hubert later transferred to the 11thBattalion of the Royal West Surrey Regiment, No. 207962, where he reached the rank of Corporal, earning the right to the Territorial Force War Medal. On being demobbed he went home to 69 Park Street.
After the war he returned to being a clerk but now worked in a bank. At the age of 30, on 5thAugust 1924 in Cheltenham Parish Church, he married Hilda Fanny Harvey, daughter of a building foreman. Most likely he left the family home after his wedding and moved to 48 East Street, Thame where he was living in 1939, still working as a bank cashier. His father died in 1927 and his mother four years later. Hubert died on 14thFebruary 1955 at the Old Bank House, Thame, leaving £1,134 to his widow. It seems that they had no children.
