Answer 2

From the Wikipedia... * He was born in rural Stillwater, Pennsylvania. * His father, Jackson Gibbs, owned a store in the same town. * Gibbs' father may have been U.S. Army Air Force . * He is apparently named after his father's friend, Leroy Jethro, who was his business partner in the store after having worked together in the coal mines. * The younger Gibbs left Stillwater in 1976 at the approximate age of 18 - 20 and did not return for over thirty years. * He was also known as a delinquent. * Gibbs speaks Russian and signs American Sign Language. * Gibbs reveals that he is a Virgo. * Gibbs has been married four times and divorced three times. * He met his first wife, Shannon, while waiting at the Stillwater Train Platform in 1976, at which point she told him about her rules for life (these would inspire a similar set of rules which he would follow later in life). * Shannon, along with their daughter Kelly, were murdered by a Mexican drug dealer while Gibbs was deployed for Operation Desert Storm. * Gibbs killed the drug dealer. * Each wife was a redhead, and he once had a romantic relationship with the now deceased director of NCIS, Jenny Shepard, who was also a redhead. * Before the time in which NCIS is set, Gibbs travelled extensively on operations, particularly in Eastern Europe, demonstrated by many flashbacks, many including Director Jenny Shepard. * He's built four boats, one of which he burned because he had named it after his ex-wife. He named one after his daughter Kelly, and never revealed what he did with it or the other two. It's also a mystery how he gets them out of his basement.
