Hampartz Ovagam Ademian was born on 15 May 1891 in Bursa, Turkey but immigrated to the United States in 1913, arriving in New York on board of ‘Chicago’ ship on 1913 with his parents Ovagam Ademian and Mary Beelbeelian.
Despite still being a Turkish citizen, he joined the British Expeditionary Forces (the British Army sent to the Western Front during WW1) as a private. There are records of him serving between 1917 and 1919. Interestingly, he’s registered as Armenian and his place of birth as Armenia in the list of US residents serving in the British Army. His profession is specified as a chauffeur.
In December 1927 Hampartz applied for naturalisation in the USA. After 1936, he changed his name to Harry Adamnite.
