Cy Denneny

Cyril Joseph Denneny (December 23, 1891 – September 10, 1970) was a Canadian ice hockey forward who played in the National Hockey Association and the National Hockey League between 1914 and 1929. Born in Farran's Point, Ontario, near Cornwall, he was the son of James Israel Denneny, a top lacrosse player of the late 19th century whose family descended from the Dennenys of County Monaghan, Ireland.

Denneny began playing senior hockey in Cornwall in 1909–10 with the Cornwall Sons of England of the Lower Ottawa Valley hockey league. He tried out for the Montreal Canadiens in 1912 but failed to make the team and returned to senior hockey. His professional career began in 1914 with the Toronto Ontarios/Shamrocks of the National Hockey Association, the club's name changing during the season. He was traded to the Ottawa Senators in 1916 and went on to play for Ottawa and the Boston Bruins in the NHL from 1917 to 1929.

Over his career Denneny won the Stanley Cup five times, four with Ottawa and once with Boston. His younger brother, Corbett Denneny, also played in the NHL. He was inducted into the Hockey Hall of Fame in 1959.
