Nancie goes out into the big, wide, world

The first of these photographs was taken about 1916 or 1917. I'm not sure if it was taken before or after the death of their Father but  Nancie, Bill and Nell do not look very happy.  The second one is from about  1920 and although all three look fairly serious the two girls are beginning to blossom. It's best clothes and bows in the hair for them and a suit with a collar for Bill.
