Four children were born to the devoted couple, all sons; the first child lived, as we have seen, only six months; the second was named Carl; the third was named Leopold; the fourth, Wolfgang Amadeus. Nohl says, "His wife's recovery on these occasions was always very tedious." In 1787 Mozart's father died, and his letters to his sister show the depth of his grief. Nannerl had married three years before. Her first lover had relinquished her on account of her poverty, but she had captured a widower of means and position.
