Are former Montreal Canadien Mats Naslund and Canuck captain Marcus Naslund related?

These two are both Swedes, and Mats was born in the 1950's and Marcus in the 1970's, so the age difference is right. I remember back in his days with the Habs Mats' wife gave birth to a baby boy. Does anyone know the answer to this question or where I can find the answer?
