How much of a job to take up the first floor boarding? Adding
additional noggings between the ceiling joists might beef it up, and
you could also insert some sound insulation.

Taking up a single board in the right place, glueing in herringbone
strutting, and anchoring the end joists to the walls *will stiffen up the
ceiling considerably, possibly enough to stop the cracking.

It is easier to fit strutting tight across the gaps between joists than it is
to fit tight noggins.

Cut noggins 1/16 over and bray with a lump hammer.
