ihatehousework2, the Guardian title of Jack Straw's article gives the wrong impression. It seems to imply that Saint George was Turkish, and he was not.
Look at wikipedia
"Saint George (Greek: ???????? (Georgios), Classical Syriac: ??????? (Giwargis), Latin: Georgius; c. 275/281 – 23 April 303 AD), born in Lydda, Roman Palestine, was a soldier in the Roman army and was later venerated as a Christian martyr. His father was Gerontius, a Greek Christian from Cappadocia, and an official in the Roman army. His mother, Polychronia was a Christian from Roman Palestine.[3] Saint George became an officer in the Roman army in the Guard of Diocletian. In hagiography, Saint George is one of the most venerated saints in the Catholic (Western and Eastern Rites), Anglican, Eastern Orthodox, and the Oriental Orthodox churches. He is immortalized in the tale of Saint George and the Dragon and is one of the Fourteen Holy Helpers. His memorial is celebrated on 23 April (May 06), and he is regarded as one of the most prominent military saints."

And from wikipedia aboutTurkey and when the Turks migrated to the Turkey, much later than when St George lived.
"The Seljuk Turks began migrating into the area in the 11th century, starting the process of Turkification, which was greatly accelerated by the Seljuk victory over the Byzantines at the Battle of Manzikert in 1071.[16] The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, upon which it disintegrated into several small Turkish beyliks.
Starting from the late 13th century, the Ottoman beylik united Anatolia and created an empire encompassing much of Southeastern Europe, Western Asia and North Africa, becoming a major power in Eurasia and Africa during the early modern period. After the Ottoman Empire collapsed following its defeat in World War I, parts of it were occupied by the victorious Allies. The Turkish War of Independence, initiated by Mustafa Kemal Atatürk and his colleagues, resulted in the establishment of the modern Republic of Turkey in 1923, with Atatürk as its first president."
