The Lopezes have been dubbed the "First Family of Taekwondo."
They're the first trio of siblings from America to compete in the same Olympics since Edward, Richard and William Tritschler did it in gymnastics in 1904.
Steve is a two-time Olympic champion after winning in both 2000 and 2004. Mark and Diana will be competing in their first Olympics. Diana was an alternate in 2004.
Oldest brother Jean is their coach.
State Representative Charlie Howard of Sugar Land and Senator Rodney Ellis of Houston issued a proclamation for: "Lopez Family Be Hospitable Day."
Sugar Land Mayor David Wallace issued a similar decree for the Houston-aera city.
