There are only a few father and son combinations not only to have played in the NHL but to have won a Stanley Cup. Lionel and Brian Conacher and Bobby and Brett Hull certainly are two of the more notable fathers and sons to have both enjoyed Stanley Cup victories. Here's one more combination to add to the list: Jack and Fleming MacKell.
Jack won two Stanley Cups while with the Ottawa Senators in the 1920s, while Fleming won two Cups as part of the Toronto Maple Leafs roster -- one in 1948-49, the other in 1950-51. Fleming MacKell played junior with St. Michael's College in the Leafs' organization, joining Toronto as an eighteen-year-old in 1947-48. But after becoming a regular, MacKell was traded to Boston where he played for eight and a half seasons.
It was as a Bruin in 1952-53 that MacKell was selected to the NHL's First All-Star Team.
