Shemavon Danielian was born on 15 January 1890, in Konya, Turkey. He served as an interpreter during WW1, enlisted in early April of 1915 and was sent to the theatre of Gallipoli. He was discharged at the end of 1919. His address is listed as Baghdad where he lived with his wife Mary Ekmekjian, who was born in 1898, in Egypt. Their son Jirair was born in 1926 in Baghdad, however, the couple travelled back to the UK, where Shemavon passed away in 1967.
Records of an intelligence officer called S. Danielian exist from WW2, however, we are unable to say for certain at this time that is is Shemavon.
