Our story of Jahsiah
Our story of Jahsiah is a story of two names for God meeting. Josiah is a king of Judah who finds a lost law-book in the temple and reforms the kingdom on the strength of it; his name carries the Hebrew divine name. Jah is the Rastafari form of the same word, taken into American naming from the 1990s. Jahsiah puts them together, and appears in the registers in the 2000s.
Meaningscholars disagree
Not established
The -siah ending descends from Josiah, from the Hebrew Yoshiyahu — 'the Lord supports' — and carries the divine name. The Jah- front is the Rastafari name for God or a modern American sound. The compound is recent; only the ending has an origin.

The Rondel test
Every popular name lives one long story — a climb, a peak, a slow settling back. Jahsiah's later chapters haven't been written yet, so we borrowed them: Rondel climbed just as high around 1940, and its whole arc is on record. Line the two peaks up, and Rondel's path sketches the road Jahsiah is walking now.
