This name appears in the New Testament belonging to a companion of Saint Paul. He became the first bishop of Crete and was the recipient of one of Paul's epistles. This was also the praenomen of all three Roman emperors of the 1st-century Flavian dynasty, and it is the name by which the second of them is commonly known to history. Shakespeare later used it for the main character in his tragedy Titus Andronicus (1593). As an English name, Titus has been occasionally used since the Protestant Reformation.
In the English-speaking world this name has been occasionally given since the early 20th century. It started rising in America after the variant Lorelai was used for the main character (and her daughter, nicknamed Rory) on the television series Gilmore Girls (2000-2007).
This is also an alternate transcription of Russian Ева (see Yeva).
As an English name it was highly popular from the Middle Ages until the 17th century. It was revived in the 19th century and was common into the 20th, but it fell into decline after the 1930s. It last appeared on the American top 1000 rankings in 1972.
