Actor Mark Harmon is known to most as Leroy Jethro Gibbs from the hugely successful TV show NCIS. But did you know he comes from a very famous family? His father was NFL star and broadcaster Tom Harmon. Recently, Mark spoke to People magazine about the profound – and slightly profane – advice his father imparted to him. It sounded like it could have come from a NCIS scene between Gibbs and Jackson, but it was real. And he’s carried it with him throughout his whole life.
The Harmon family tree is dotted all over with famous faces. At the top there’s football star Tom and his wife Elyse Knox, an actress. Then there’s Mark himself of course. And Mark’s sister Kristin wed The Adventures of Ozzie & Harriet actor Rick Nelson. From that union came actress Tracy Nelson and rockers Matthew and Gunnar Nelson.
Mark is also married to someone from the celebrity world. In 1987 he got hitched to Mork & Mindy actress Pam Dawber. They have two sons, screenwriter Ty and actor Sean. You won’t catch any of the Harmons on Facebook or Instagram, though. The whole family intensely maintain their privacy.
