Just filling in some history on Olga
"Ahmet Naci Bey , was a promising foreign service officer working at the Ministry of Foreign Affairs. During the Lausanne Peace Conference in 1922, he served as the Private Secretary to İsmet İnönü. When World War I broke out, he was studying at Glasgow University in Scotland and wanted to return to Turkey, but at the insistence of his father, Mehmet Galip Bey, he moved to London and began working at the embassy there. However, fate intervened; instead of becoming an electrical engineer, he became a diplomat at his father's suggestion. At a party given by a friend, he met the love of his life: the beautiful young English woman, Olga Cynthia . After a short courtship in 1920, he married her. Ahmet Naci Bey, his wife, and their three-year-old son, Jack, traveled from England to France. From Paris, they boarded the Orient Express , operated by the Wagon-Li Company , enjoying a pleasant train journey to Turkey."
"The fact that the bride was Christian, and had been married before and was a widow with one child, did not please her mother-in-law, Nuriye Hanım, at all."
