6. Carl and Laura
In the end, Family Matters aired 215 episodes over the course of nine seasons. The dominant character by a long shot, proof positive by his staying power in popular culture, was Steve Urkel. Still, Urkel did not make it into every episode. Two characters, father, and daughter, Carl and Laura were the only two who made it in every show. Reginald VelJonson played the patriarch, Carl Otis Winslow, and as discussed already, Kellie Shayne Williams played his daughter Laura Lee.
