Justin

Justin is a Latin name derived from Justinus, a derivative of Justus, meaning just or righteous, itself rooted in the Latin jus, meaning law or right. The name was borne by several early Christian saints and martyrs, most notably Justin Martyr, a second-century philosopher and apologist, which helped spread its use throughout the Christian world. It was also the name of two Byzantine emperors, further cementing its prominence in medieval Europe. Related forms include Justus, Justinian, and the French Justine.
