The Connollys are diehards, for sure, and they have tried to pass on their fandom to their nephews, who used to attend games with "Aunty Karen" and "Aunty Mo" almost every Saturday afternoon.
"Four generations going now," said Maureen, who listed Orr, Bourque, and Patrice Bergeron as the sisters' three all-time favorite Bruins. "The rule to come with Aunty Karen and Aunty Mo, you had to be potty trained, you couldn't go to the hockey game in diapers. The third generation is now bringing their kids. My nephews were like four, five, three, six - we would just walk them right through.
"They would go to every afternoon game. We didn't pay for them or anything. They sat on our laps and went to practically every Saturday afternoon game."
Karen and Maureen attend about half of the home games these days, with friends and family "filling in" for the others. It's a tradition they have a tough time thinking of giving up.
"You kind of think, how much longer?" said Karen. "It's that feeling like you're giving up that family thing, that connection to my father. All the kids look at us, they're trying to make their way."
To the Connollys, it's simple: Bruins hockey is part of their identity.
"Bobby Orr was it. He was the man…he started in '66, I started in '67, the Bruins started their climb and never stopped. It was Bobby. He put the spark back in the game," said Maureen.
"But it wasn't that he cemented our fandom. It's in our blood. It's something you had to do."
