History & Origin
Tyberius is a contemporary respelling of Tiberius, a Latin name drawn from Rome's river. The emperor Tiberius ruled in the first century, and the name found a second life in science fiction as Captain Kirk's middle name. The Ty- form is modern and has no separate root of its own (said 'ty-BEER-ee-us').
It is rare for boys in the U.S., against light use of Tiberius itself. Rare, grand, and modern-spelled.
