The Holt Family is a family of five (six, including Arnold, the family pet, who is a pitbull) who joined the 39 Clues Hunt. They're known to be buff, strong, not very bright (in some cases), and speedy. Eisenhower seems to be the leader.
The Holt family is one of the nine teams to accept the challenge from the will of Grace Cahill in 'The Maze of Bones' and joined the search for the 39 Clues. They are the only Tomas team, and are usually shown as brawny with little brains and big muscles. However, Hamilton is revealed to have a talent for working with computers, especially hacking. In the beginning, they all fought together as a family, but later on in the books, Hamilton started to make his own decisions and made an alliance with Amy and Dan Cahill. They were the first ones to access the island.
Later, after the Clue Hunt, it is revealed in The Black Book Of Buried Secrets that Hamilton and his family enter the Mt. Fuji, Tomas stronghold despite their outcast reputation. Working for the Madrigals now, they overpower Ivan Kleister's taunts and commands and begin to tell the other fellow Tomas in the stronghold about how making the Cahill family united again was the number one priority and how the Clue Hunt has been poisoning the family for generations.
They are very strong and talented in physical activities.
