Ruediger of Saxony and his succession rights
 

If I understand the succession law in Luxembourg correctly, the succession is restricted to the heirs-male of Grand Duke William IV's daughters.

So, are the heirs-male of Crown Princess Sophie of Saxony in the line of succession to the throne of Luxembourg after the heirs-male of Charlotte? In other words, are Prince Ruediger of Saxony and his sons in the line of succession?

Theoretically the male line heirs of Princess Sophie can succeed to the throne in Luxembourg; the problem is that all her descendants were born from morganatic marriages, so I really don't know if Rudiger can succeed or not.
