Good list, but Gretzky's ancestor were from Belarus.
"Wayne Gretzky, the legendary Belarusian-Canadian ice hockey player, has met his Belarusian relatives during a visit to Belarus, Komsomolskaya Pravda v Belarusi reported. Gretzky’s grandfather Anthony Gretzky (Ciarenci Hrecki) was a Belarusian immigrant to Canada. Wayne Gretzky’s Belarusian relatives still live in the Hrodna province of Belarus."
