Chris Duffy (born 21 October 1918 in Methil, Fife, Scotland) was a Scottish footballer who played as a left winger in the Football League. He scored the only goal for Charlton Athletic in extra time in the 1947 FA Cup Final, against Burnley.
Duffy, a fast and intelligent winger, first came to Charlton Athletic as a war time quest player. A modest fee of £330 persuaded his home club, Leith Athletic to relinquish his services when he was demobilised from the armed forces. His appearance against Burnley was his third Cup Final. He aided Charlton against Chelsea in the 1944 "South" Final and against Derby County the following year.
Later on in life he lived very happily with his two children and his wife before dying in Northern Ireland, Bangor, 1978
At first, Chris Duffy had another wife, who was married to him at the time when he scored the winning goal, with whom he had three children. So in fact, he had five children.
