Erskine Rockcliffe Ronan (February 9, 1889 – June 25, 1937) was a Canadian professional ice hockey player who played 10 professional seasons from 1908 to 1919. Ronan played the majority of his professional career in the National Hockey Association (NHA) and played one season in its successor league, the National Hockey League (NHL) in 1918–19 as a member of the Ottawa Senators. He won the Stanley Cup in 1916 with the Montreal Canadiens. He was born in Ottawa, Ontario. Playing career Ronan made his professional debut as a defenceman with the Pittsburgh Bankers of the Western Pennsylvania Hockey League (WPHL) in 1908–09, then would break his contract to leave to play with the Toronto Professionals, finishing with a few games for the Haileybury team in the Temiskaming Professional Hockey League (TPHL). He would stay with Haileybury in 1910 in the inaugural season of the NHA. In 1911, Ronan remained in the NHA after Haileybury returned to the TPHL, as a member of the Renfrew Creamery Kings in their final season in the NHA. For the 1911–12 season, Renfrew dropped out of the league and its players were dispersed to the remaining clubs in the league by drawing lots. Ottawa picked Ronan after the Wanderers had picked Cyclone Taylor, and tried to trade Ronan to the Wanderers for Taylor without success. Ottawa's regular centre Marty Walsh was not playing well and Ottawa tried Ronan out at centre. Ronan blossomed at centre, scoring eight goals in one game and five in another, ending up with 35 goals in 18 games. While a member of the Senators during the 1911–12 and 1912–13 seasons Ronan was also a member of the NHA Eastern All-Stars, managed and coached by Art Ross, who played series of exhibition games against an All-Star aggregation from the Pacific Coast Hockey Association, scoring a total amount of 8 goals in 9 games over two years. Ronan would play two more seasons with Ottawa before being sold to the Toronto Shamrocks before the 1914–15 season, but did not duplicate his goal totals. Ronan played a season and a half with the Shamrocks and the rivaling Toronto club Toronto Blueshirts before being dealt to the Montreal Canadiens, playing on their 1916 Stanley Cup-winning squad, scoring a goal in the deciding game 5 2-1 win over the Portland Rosebuds.
