Back to Maria Luisa, Countess of Bardi. Yesterday I came across the English Wikipedia article of Maria Luisa that refers to a book written by Giovanni Spillmann in 1875.
It is told that Henri and Maria Luisa spent their honeymoon in Egypt where Maria Luisa was affected with a fever. She was taken to the French town of Cauterets where she had to take sulphur baths. She was also brought to Lourdes where she was emmersed into the holy water. Finally when her doctors said that there was no hope for her anymore, she was brought to Pau where she died on 23 February 1874.
Has anyone of you collected some more information about Maria Luisa? Does anyone know Spillmann's book?
