Notice, that in Old Testament, written down by Jews you will not find any mention of daemons, in the best case some tiny hints, but no any real discussion or description. Only in New Testament, written down by people of different etnicity the whole question of daemons pop up. Jesus exorcize daemons from people in real time. So daemons presence was something wide spread at the time, but somehow Jews-written Old Testament omit that topic completely.

And no, Joseph is not Jesus dad. You will not find a single letter in New Testament hinting that Joseph have anything with the Jesus advent.
