Boys Luke

The author of Luke is traditionally known as Luke himself.  Scholars think that the author of Luke was actually someone who was a personal witness to Jesus' acts.  Although  their are disputes concerning wether Luke was the author of Luke or not.  Paul was one of the followers of luke but he eventually did not wrote luke. Luke probably wrote down all of jesus' acts from his view point, and to his understanding. in the end wee really do not know, because everything as you said in chapel is a hypothesis, and it is not proved. Another thing is that we se a lot of stuff repeated, it is probably there for a reason.
