Garapet was born in the Ottoman Empire and was still an Ottoman subject in 1911; his wife Elizabeth Sarah, born in Cork, Ireland, was a British subject ‘by parentage’. All their three children are listed as ‘British born’, which would give Krikor the right to to enlist in the British Army.
He enlisted in 1916, specifying his profession as a teacher of Chemistry. Krikor served as a Pioneer in the Royal Engineers Corps, which maintained the railways, roads, communications etc. (Regimental Number 224948) and was awarded the British War Medal and the Victory Medal. It is unclear when he returned from the army, but in 1918 he is registered as living in Fulham.
In 1925 his mother passed away and his father died the following year. Also in 1925, Krikor married Elfrida V D Starkey in Doncaster, where he was living by then and their daughter Mary was born in 1927. The exact date of his death is unknown.
