From Trevor Loudon’s site Key Wiki, very well researched site. I would trust Loudon’s research. If you have some research that disputes this, please post it.

Early Life
George Soros’ father was named Tivadar Schwartz, a successful attorney and an Orthodox Jew who, in 1936, changed the family surname from Schwartz to Soros in order to enable his family to conceal its Jewish identity and thus to survive the Nazi Holocaust. Soros sounded Hungarian, but was obscure. It means “soar” (in the future tense) in Esperanto, the made-up trans-European language promoted by those who dreamed of a world free of nationality. Tivadar was among its leading proponents.[5]
When the Nazis occupied Budapest in 1944, Soros’ father decided to split up his family, so as to minimize the chance that all its members would be killed together. He purchased forged papers for each of them and then bribed a government official to claim George as his Christian godson and to let the boy live with him.
“While hundreds of thousands of Hungarian Jews were being transported to death camps,” reports the Sweetness & Light website, “George Soros accompanied his phony godfather on his appointed rounds, confiscating property from the Jews.” (Many years later — in December 1998 — a CBS interviewer would ask Soros whether he had ever felt any guilt about those circumstances. Soros replied: “[T]here was no sense that I shouldn’t be there, because that was — well, actually, in a funny way, it’s just like in markets — that if I weren’t there — of course, I wasn’t doing it, but somebody else would — would — would be taking it away anyhow. And it was the — whether I was there or not, I was only a spectator, the property was being taken away. So the — I had no role in taking away that property. So I had no sense of guilt.” Soros has repeatedly said that 1944 was the best year of his life.
But he was a “Nazi”.
