Enoch shows up a couple of times in the Bible.

a) he is a son of Cain and also a city (Genesis 4:17)---
And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch.

b) he is the son of Jared and father of Methusaleh (Genesis 5:18, 21)---
18 § And Jared lived an hundred sixty and two years, and he begat Enoch:
21 § And Enoch lived sixty and five years, and begat Methuselah:

This Enoch is fairly well-known for having "walked with God" (Genesis 5:22-24)---
22 § And Enoch walked with God after he begat Methuselah three hundred years, and begat sons and daughters:
23 § And all the days of Enoch were three hundred sixty and five years:
24 § And Enoch walked with God: and he was not; for God took him.

His name was attributed to the the Books of Enoch.
