no why
I got the following information googling "Mozart's children"
What were the names of W.A. Mozart's children and were they also musically inclined? The names were Raimund Leopold(b/d 1783), Karl Thomas(1784-1858), Johann Thomas Leopold(b/d 1786), Theresia Constanzia Adelhied Friedericke Maria Anna(1787-1788), Anna(b/d 1789), Franz Xavier Wolfgang (1791-1844). The two survivors were Karl and Franz. Karl became minor official on staff of viceroy of Naples in Milan. Franz composed and conducted throughout Europe but never got the fame of his father.
