Tiberius

Tiberius Caesar Augustus (November 16, 42 BCE – March 16, 37) was a human who lived on Earth during both the 1st century BCE, and the 1st century CE. Tiberius was the second Emperor of the Roman Empire, succeeding the Emperor Augustus in the year 14, and ruling until his death in the year 37. Tiberius was noted for being a particularly bloodthirsty Roman Emperor. (ENT episode Last Full Measure).

In the 23rd century, George Samuel and Winona Kirk gave their second son James the middle name of Tiberius as George's father Samuel was fascinated with the Emperor Tiberius. (Star Trek: The Motion Picture novelization). When a disguised Charles Tucker met the Kirk family, he wasn't sure what was worse for the young James Kirk, having been born on March 22nd - which had been the day of the Xindi attack on Earth, or that he had been named after Tiberius. (ENT novel Last Full Measure).

In the continuity of the novels written by William Shatner, the James T. Kirk of the mirror universe used the name Tiberius as his regnal name. (TNG novel Star Trek: Spectre).
