Istvan Petnehazy changed his nationality four times since WW1 Istvan Petnehazy, 86, was born and has lived his life in the same house in the same village (Mezokaszony in Hungarian, Kosino in Ukrainian), less than a kilometre into Ukraine from the Hungarian border. Although born in 1932, over a decade after the end of World War 1, he keeps mementos of the Austro-Hungarian Empire era including military photographs of his grandmother's brothers who as teenage schoolboys were conscripted into the imperial army. Since the end of World War 1 and the break-up of the Austro-Hungarian empire, Kosino changed countries - and Petnehazy his nationality - four times: Czechoslovakia, Hungary, the Soviet Union, and finally Ukraine.
