Charles Tucker II was the son of Charles Tucker I and father of at least three children, including Charles "Trip" Tucker III and Elizabeth Tucker. His eyes apparently bore a close resemblance to those of Lorian. (ENT: "Fusion", "First Flight", "E²")

When his son was a child, Tucker encouraged him to become an engineer. (ENT: "Similitude")

In 2153, Tucker and his wife lost their daughter Elizabeth in the Xindi attack on Florida. (ENT: "The Expanse")

Following the attack, he and his wife moved to Mississippi. (ENT: "The Augments")

Tucker lost a second child in 2161, when Trip was killed in the line of duty aboard Enterprise NX-01. He and his wife attended the signing of the Federation Charter soon after. (ENT: "These Are the Voyages...")
