James T. Kirk/Relationships/Family

The Kirk family ancestry included settlers who pioneered the American frontier in the 19th century, and the Kirks of the early 23rd century rediscovered the impulse for untamed spaces. After his early childhood on Earth, Kirk lived on Tarsus IV by the age of thirteen, and his brother's family later lived on colonies as well. ()
