Jermiah, of Hebrew origin, means 'appointed by God' or 'may God exalt'. It is a variant spelling of Jeremiah, the prophet whose story is chronicled in the Bible's Book of Jeremiah. Jermiah gained prominence during the 19th century and has since been used sporadically.
"The name Jermiah experienced fluctuations in popularity over the years, with peaks in 2001 and 2003, and a more consistent trend of five births per year from 2010 onwards."
