No, Seferis's family was originally from Turkey. He was born in Smyrna, which is now İzmir, Turkey. His family was of Greek descent and they had lived in Smyrna for many generations. However, in 1922, during the Greco-Turkish War, Smyrna was captured by the Turkish army and the Greek population was forced to flee. Seferis and his family were among those who fled to Greece.
