A new baby and a new house

Constanze delivered their second child, Karl Thomas, on September 21. Karl Thomas will live to the ripe old age of 74, unlike his brother Raimund. His parents moved house very early in his childhood, again. This time it was to the Domgasse which was much more salubrious. And salubriousness brought expense with it, with the flat costing a staggering 450 gilder a year for the Mozarts.
