Shemavon Danielian was born on 15 January 1890 in Konya, Turkey. He served as an interpreter during WW1, enlisting in early April, 1915 and being sent to 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 Egypt in 1898. Their son Jirair was born in 1926 in Baghdad; however at some stage the couple must have travelled to the UK, because Shemavon died there in 1967.
Records of an intelligence officer called S. Danielian exist from WW2, however it is difficult to confirm 100% whether or not it is Shemavon.
