1. The Mayweathers
Fans of the Alis might not like this, but the Mayweathers are boxing’s greatest family. Spanning two generations, Roger, Floyd Sr., and Jeff all had decent professional careers. The former in particular was a top fighter, becoming a two-weight world champion. Now they’re all boxing trainers.

Of course, Floyd Jr. brought the family’s name to the next level. The five-weight champion won an incredible 15 titles and retired with an unbeaten record of 50-0. In short, Floyd Mayweather Jr. is one of the best boxers of all-time. Love them or loathe them, this family is truly something special.
