The relationship between their parents is quite intriguing. Maximilian had numerous mistresses & Ludovica was deeply hurt by this but, during the early years at least, she kept accepting him back. In later life they never spoke to each other at all despite maintaining a semblance of normality, & Maximilian preferred the company of his illegitimate children.
All these Bavarians are so very very strange & fascinating partly because so many of them were -basically - completely 'round the twist'!
Ludovica suffered from such terrible headaches that she could not bear anyone even to touch her hair. I wonder if there was some kind of inherited 'brain' problem (apart from all the previously discussed theories of the effects of such much in-breeding.)
Also, I would be very interested to know a lot more about Sissi's cousin, Alexandrine (1826-75) daughter of Ludwig I of Bavaria, who had to be confined because she thought she had swallowed a glass piano :-/ :-/
(This sounds so bizarre, I wonder if she meant like a little model one :-/ - Surely, not a full sized glass piano? It's really sad that she thought that - I mean REALLY sad - but it makes me laugh.... :-/)
