Gadot was born on 30 April 1985 in Petah Tikva,[note 1] where she first lived. She was later raised in the city of Rosh HaAyin. In Hebrew, her first name means "wave" and her surname means "riverbanks". Her parents are Irit (née Weiss), a physical education teacher, and Michael Gadot, an engineer; they Hebraized their surname from "Greenstein" to "Gadot" prior to her birth. Her father is a sixth-generation Sabra. Gadot's maternal grandparents were born in 20th-century Europe; her grandfather, who was imprisoned in the Auschwitz concentration camp during the German occupation of Czechoslovakia, survived the Holocaust, while her grandmother managed to escape the continent before the outbreak of World War II hostilities. She has stated that she was brought up in a "very Jewish, Israeli family environment", and is of Ashkenazi Jewish descent (Polish-Jewish, Austrian-Jewish, German-Jewish, and Czech-Jewish). She has a younger sister, Dana Gadot.
