on the court of August the 2nd we can find 2 or 3 body-cooks or Leibköche, especially Posch and Noeller, their families always lived with the king. And we have some evidence that the father of their children were not the cooks, but the king:

1st - these children were nobled and got some of the highest political ranks in different monarchies

2nd - these children lost their inherit money when the mother died, who got the money from the etat of the king

3rd - it is nearly impossible to find out the origin from the mothers/maitresses

etc.
