The two biggest victories came in quick succession.

In March 2017, the twin sisters Jocelyne Lamoureux-Davidson and Monique Lamoureux-Morando helped secure better pay and benefits for themselves and their teammates on the United States women’s hockey team.

Less than a year later, at the 2018 Winter Olympics, the Lamoureux sisters scored the final two goals of a comeback victory in the gold medal game against Canada. Jocelyne’s, a deceptive pullback that gave the Americans a win in a shootout, was arguably one of the most important goals in women’s hockey history.

They had crafted — on and off the ice — the perfect denouement to their careers as hockey players.

But the Lamoureux sisters are passing on that storybook ending. In the coming months, Jocelyne and Monique, new mothers who turned 30 in July, will press for more gains for the women’s national team when the team begins negotiations with U.S.A. Hockey for a new contract. They will continue to direct a player-led push for a professional women’s league that provides livable salaries so women would not need second jobs. And they will keep on playing.

For now, that will not be in the existing women’s professional league in North America. Instead, they are part of a group of Olympians who have chosen to compete in a series of exhibitions and showcases to promote their sport across North America, a tour that began last week in Toronto. The Lamoureux sisters say they also are seeking to further redefine perceptions surrounding athletes and motherhood.
