I've found out a bit more information about T.G. Moore's wife and family as follows.
He married a woman called Evelyn M Coustas in 1948 in Fulham, west London. Two children births were registered in Marylebone district in 1951 and 1955.
Evelyn Coustas appears to be a classical/ballet dancer. I've found a listing which shows that she took part in Liszt's "Apparitions" ballet performed by the Sadler Wells ballet company in 1940. This had been choreographed by Frederick Ashton and Evelyn Coustas apparently danced alongside Margot Fonteyn in this production.
Evelyn Coustas was the daughter of Alexander Pantelis Coustas.
Alexander Coustas was born in Liverpool in 1874, son of Timothios Demetrius Coustas and his wife Josephine Hackenburg. He was a Staff Sergeant Major for the Royal Army Service Corps during the Great War. At the conclusion of the war he appears to have been articled to J.J. Stavridi, Solicitor, 40 Old Broad Street, London, EC. He subsequently went into partnership with Demetrius John Cassavetti and formed Cassavetti, Coustas & Co, Solicitors, 15 St Helen's Place, London, EC3. His wife's name on the electoral rolls is Jane Argyri Coustas and they seem to have lived in west London until the mid-1950's. I've not been able to locate marriage or death indexes for either, nor have I been able to find the birth index for their daughter Evelyn.
Timothios Coustas and Josephine Hackenberg married in 1870 in Kensington, London then had 5 children between between 1871 to 1879, all born in the Liverpool/West Derby area. The family were living together near Southport, Lancashire at the time of the 1881 census. Timothious and Josephine were divorced in 1887. Josephine was admitted to the Chelsea poorhouse in January 1891, the record shows she was destitute. By the time of the 1891 census, Josephine and three children were living at 157 King's Road, Chelsea. The 1911 census shows Josephine, Alexander & the youngest daughter, Marigo living in Carshalton in Surrey. At this time Alexander was an educational coach and Marigo was a teacher of music and languages.
Any further snippets of information on the above would be appreciated.
