Josiah
Meaning
“God supports”
The story
Josiah comes from the Hebrew Yoshiyahu, meaning Yahweh supports. Its biblical bearer was a king of Judah remembered for sweeping religious reforms. The name itself preserves an old divine element in a compact form. English Protestants adopted the name after the Reformation, but American use stayed quiet for centuries. The chart barely moves until the 1990s, then rises in the 2000s, climbs again in the 2010s, and reaches its strongest point in the 2020s. Josiah is part of the modern return of long biblical names, but it has a different texture from older standbys such as John or David. The soft ending and the easy short form Josie give an ancient royal name a surprisingly gentle sound. Its history is old; its broad American life is new.
