When Marion was playing, I heard his Dad say that their youngest son, at that time in 8th grade, was actually the best athelete at that age of any of his sons. He must be in High School now. How is he doing??
Dominique's father also said that his youngest son, Thomas, just started playing hockey. But Marion Barber Jr. said that his 10-year-old is "ultimately waiting in anticipation for his chance to suit up for Minnesota," and continue the family tradition.
Here's an article from 2007 where Marion Barber talks about his youngest son. His name is Thomas. He would be 14 years old now.
