I want to know the answer to the following question:
What was the name of Sand's daughter's fiance that contributed to deteriorating the relationship between Sand and Chopin?
All the background I'm provided with is that "In 1847 Sand published her novel Lucrezia Floriani, whose main characters—a rich actress and a prince in weak health—could be interpreted as Sand and Chopin; the story was uncomplimentary to Chopin, who could not have missed the allusions as he helped Sand correct the printer's galleys.". Is that enough to answer the question?
Answer: no
