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. On the negative side, British politician Enoch Powell gave the infamously racist Rivers of Blood anti-immigration speech, taking the name out of consideration for many parents in the UK.

A name from Greek mythology, much more melodic than its later form Denise. With mythical names on the rise, this would make an interesting lesser-used option.

An ancient Roman forename never (yet) used in the modern world.
