Although most connections are among players, there have been family members involved in coaching and managing as well.
Since 1917, 47 pairs of brothers have played together on the same team; among them, ten have won the Stanley Cup together.
The original six brothers (Brent, Brian, Darryl, Duane, Rich, and Ron) and three of their sons (cousins Brandon, Brett, and Brody) result in multiple brother/father-son/uncle-nephew/cousin combinations.
Below is a list of family relations throughout the NHL as players, head coaches, general managers, and officials.
This category is for such pairings not already listed in the "Parent-Children" section above (i.e., maternal grandparents): grandfathers Paulin Bordeleau, Bernie Geoffrion, Bryan Hextall, Lester Patrick, Jerry Wilson.
