A very common boys' name (and nickname) in Nigeria that some Americans will recognize as the name of one of the main characters on NBC's The Good Place.

There is much disagreement about the origin, meaning, or even existence of this name. Some sources cite Jesiah as the name of several minor Biblical figures, others say it's a variation of Josiah, still others call it a modern conflation of Josiah and Jesse.

The origins of Jesiah are uncertain — is it biblical? A Josiah-Jesse mashup? We don't have the answer (sorry!), but we can tell you that Jesiah is a relatively rare alternative to Josiah, with the added benefit of being unisex in use.
