In September of 2015, Canadian Olympic ice hockey player Meaghan Mikkelson gave birth to a baby boy.
She and her husband chose the name Calder with the help of Twitter users.
Calder — as in the Calder Trophy, and the Calder Cup — can be traced back to Frank Calder, first President of the National Hockey League.
