Jedidiah, an Old Testament name with a touch of Gunsmoke-era western panache, is right in line to be revived along with the other biblical -iah names. It's currently Number 716, climbing significantly since its reintroduction to the popularity list in 2010.
Jedidiah was the name given by the prophet Nathan to King Solomon in the Old Testament. An inspiration to hiking enthusiasts might be the intrepid explorer and trailblazer Jedidiah Strong Smith.
Jed is the inevitable nickname, which last ranked on the US popularity charts in 1989.
