Jeremial is of Hebrew origin, derived from the name Jeremiah, which means 'appointed by God'. It is a variant spelling of Jeremias, a form used primarily in France and Belgium. The name Jeremial was popularized during the Middle Ages through the Latin form of Jeremiah's name, Hieremiah, which was used in some early Christian texts.
"Jeremial is quite rare; only six babies were named Jeremial annually in 1984."
