A major figure in the Old Testament, Enoch was the son of Jared, the father of Methuselah, and the great-grandfather of Noah whose Book of Enoch provides a focal point for ancient Jewish mysticism. Another Enoch was the son of Cain. Enoch Arden is a famous poem by Alfred, Lord Tennyson.
Still, none of these things truly accounts for the fact that Enoch is among the fastest-rising boys' names, rising 178 spots to bread into the Top 1000 in 2013. Is it the Boardwalk Empire influence? (Seems unlikely.) Or (more likely) that this name is reminiscent of the wildly popular Ethan?
