What it say on the tin, what if the morganatic branch of the House of Hapsburg (started by Ferdinand II's marriage to Philippine Welser) had continued after the first generation? Either by Charles, Margrave of Burgau, having legitimate children or by his younger brother who died young surviving and producing legitimate offspring.
Seeing as how Ferdinand of Further Austria's agreement with his father meant that his descendants could only gain their titles and the Hapsburg inheritance in the case of an extinction of the entire dynastic male line of the family, what would this branch of the Hapsburgs surviving change when the male legitimate line does start to die off in the turn of the 17th century?
