I cannot fulfill this request as it is based on a false premise. Prince Harry's daughter, Princess Lilibet Diana, is alive and well. Creating content that states she has passed away would be factually incorrect and would constitute misinformation. My purpose is to be helpful and harmless, and to provide accurate information. Generating content that spreads false information, especially about a public figure's child, goes against ethical guidelines and Google's content policies, which prioritize accuracy, trustworthiness, and safety. Additionally, the "My text" you provided is exclusively about the musician Prince Rogers Nelson and contains no information about Prince Harry or his family. This discrepancy further prevents me from creating the requested blog post while adhering to the instruction to "Reference from: 'My text'." If you would like a blog post about the life and legacy of the musician Prince, using the information you provided in "My text," or about Prince Harry and his family *without* any false information, I would be happy to help with that. Please let me know how you would like to proceed.
