The Essenes did live in the Dead Sea area so a lot of Dead Sea scholars and professors of Jewish history attribute the scrolls to the Esseness. The Esseness were a Jewish sect, they followed the oral law but felt that all men should be celibate, always tahor, lived in isolation from the rest of the world and live their life as builders (carried an ax everywhere they went) waiting for the day when they can rebuild the third temple. They believed they were going to be builders of temple and only people who were pure to the best of their ability from birth could build the temple.
The scrolls do not as far as I know mention anything to do with christianity.
