Just call it a sister thing. Whenever another hockey team has sisters on the rosters, Jocelyne Lamoureux-Davidson and Monique Lamoureux-Morando take notice.
Well, the U.S. Olympians are twins themselves. Combine that with how few sisters play hockey or reach national teams playing internationally, it's easy enough to notice whenever sisters are dressing up for another country.
The Lamoureux sisters will have some sisterly company at the 2018 Pyeongchang Games. Teammate Hannah Brandt's sister, Marissa, plays for the unified Korean women's team, and Switzerland has two sets of sisters on the roster with Nina, Isabel and Monika Waidacher, plus twins Laura and Sara Benz.
