Where it comes from
From ius to Justus
The story of Justus
Ius is one of the most productive Latin roots in English legal vocabulary and almost none of it is obvious. A judge is a ius-dicens, one who says the law. A jury swears. Jurisdiction is where the saying of law reaches. Perjury is swearing falsely. And injury is in-iuria, not-right — so the ordinary word for a broken arm is, underneath, a legal term about a wrong done. Justus itself was a name Roman citizens carried and early Christians adopted, and it turns up in Acts as the extra name of men working in Greek-speaking cities who needed one. It went into English with the Reformation and has been quietly used ever since.
Meaning
just, righteous
Latin iustus, upright or lawful, from ius, law or right. It was a Roman cognomen and then an ordinary early Christian name, and it appears three times in the New Testament as a second name for men who also had Jewish ones.

What happens to a name after it peaks
The Davette test
Every popular name lives one long story — a climb, a peak, a slow settling back. Justus's later chapters haven't been written yet, so we borrowed them: Davette climbed just as high around 1968, and its whole arc is on record. Line the two peaks up, and Davette's path sketches the road Justus is walking now.
