Thank you for all that information Ella! Don't worry about posting all the decendants, only those of Cecily and the Crown Prince who would have been Kaiser, and possibly who is the 'heir' to that throne today?
No problem! It's big so I'm breaking it up. You'll notice that Cecile's eldest son Wilhelm renounced his rights to marry a commoner thus all his descendants were excluded and the current "heir" to the throne goes through his brother, Louis Ferdinand (who made a very good post-war marriage to Kyrill & Ducky's daughter Kyra). It's also interesting when you look through the descendants, even to the current day, the "old" royal names that persist (Cecile, Anastasia, Alexandrine, Thyra, etc...) It keeps giving me the "sunglasses" smiley, so wherever you see that, substitute an "8".
