The Nativity play we're doing looks back at the prophecies of a great King to David and Isaiah.
This exacerbates the problem there always is with Nativity plays - lack of female (biblical) main characters (i.e. not just members of crowds).
Male parts: David, Samuel, Nathan, Isaiah, Gabriel, Joseph; also shepherds & wise men
Female parts: Mary
Fortunately we have more boys than girls, and the play will also have some present day characters, who can be girls.
So I was thinking - how could you do a Bible based nativity play with lots of girl parts?
Aha - the women in Jesus' family tree!
