The Islanders’ move to Brooklyn has mostly centered on the loss of the club’s historical ties to Long Island.

The team’s owners would like to have you embrace continuity as the team opens a new chapter not too far from its old home.

In fact, the move to Brooklyn is a new chapter – there is a historical connection between hockey and Brooklyn.

The story of that connection – an almost history – is now on display at the Brooklyn Historical Society in an exhibit called “Hockey’s Forgotten Promise”.

It is the story of the remnants of the Americans –  first the New York Americans, and then the Brooklyn Americans, a hockey team that almost played N.H.L. games in Brooklyn.

The team affectionately known as the Amerks was “a colorful yet downtrodden franchise that existed from 1925-1942. They were in New York (having  moved from Hamilton) a year before the Rangers came into being and then skated as their co-tenant at Madison Square Garden.

The Americans practiced at the Brooklyn Ice Palace, about a mile from where the Islanders will now play. The former Americans defenseman Red Dutton, who also coached the team, tried unsuccessfully as the team’s league-appointed manager in the 1940s to escape the Garden and move the franchise to Brooklyn. A decade later, the Dodgers departed for Los Angeles, and Brooklyn was left without a major professional sports franchise until the Nets moved there in 2012.

While the team was called the Brooklyn Americans for a spell, they continued to play their homes games in Manhattan in the Garden.

In fact, they never were able to play a game in Brooklyn before the N.H.L. pulled the plug on them.
