  c. 1880.  Broadside Ballad, ‘The Blessed Orphan.’

        I don’t think I was born at all,
  No parents own, I came here;
I was left at a house of call,
  Close by a Pickford’s van here,
Some wicked wretches say, but I
  My indignation smother,
That I CAME THROUGH A SIDE DOOR
  In this world from the other.
