Is Wayne Gretzky Polish?

Wayne Douglas Gretzky, OC (born 26 January 1961 in Brantford, Ontario) is a retired Canadian professional ice hockey player who is currently part-owner and head coach of the Phoenix Coyotes.

Gretzky's paternal grandparents were ethnic Polish immigrants who came to Canada at the beginning of the 20th century from the town of Mogilev in the Russian Empire (now Belarus).
In a 1999 Hockey Hall Of Fame inductee press conference, Gretzky stated "Thank God I'm Polish" when a friendly joke was made about another inductee of Scottish descent who wore a traditional Scottish kilt as a dedication to his heritage.
