Nikolas Landon Brino, Lorenzo Nathaniel Brino, Myrinda Brino and Zachary Brino are the quadruplets born to Tony and Shawna Brino. They have an older half-brother, their father's son from another marriage, named Antonio, who is in the U.S. Coast Guard Academy. When the quadruplets were five months old, they were cast as twins Sam and David Camden on the television show 7th Heaven. All four of them, plus a set of twins, shared the roles until 2001. For the remaining seasons of the show, only Lorenzo and Nikolas played them.
