 Olivia, is Australian and British. John, is Italian and Irish and a little German. Her mother's family came to England from Germany to avoid being persecuted by the nazis because they were jews. Then the family eventually moved to Australia. So she's jewish on her mothers side, I have no idea if her father was a jew or not, everything says he's British. Her mother is/was definately a jewess though every newton john biography I look up says so.   Newton-John was born in Cambridge, England. Her parents were Brinley Newton-John and Irene Born (b. May 25, 1914). Irene was the eldest child of Max Born, a German Nobel prize-winning physicist who fled from Germany with his wife in the 1930s in order to avoid persecution due to Born's Jewish heritage and his wife's part Jewish descent. Olivia's father, Brin Newton-John, originally from Wales, was an MI5 officer attached to the Enigma machine project at Bletchley Park, and the officer who took Rudolf Hess into custody when he parachuted into Scotland in May 1941. After World War II, he became a professor of German at the UNSW annex at Tighes Hill in Newcastle, Australia.
