the son of the head of the family
I'm not sure, but I believe that the title of 'Furst' varies in usage among families of the nobility. In some families, especially the more recent ones since the 18th century, only the head of the family bears the title of 'Furst'. But in others, especially among the older pre-18th century nobility, all male members bear the title of 'Furst'. I'm guessing that the same may apply to the title of 'Prinz'.
