Here is the response to my email to Hilary Spurling's agent! People are truly wonderful and I thank Hilary and her agent for taking time to respond.

Dear Michael Daconta,
Thanks for this, which I passed to Hilary Spurling. She says: "I don't think his information is right because Matisse had only one brother & two nieces, neither of them called Olimpia - so whoever this Olimpia Matisse may have been, the painter can't have been her uncle. Would he like me to forward his letter to the Matisse archive?"
Good wishes,
Alice Wilson
