We have been looking for information on her too and discovered your message. My husband's mother, Anne Evelyn Browne was from Memphis. Her family acquired a painting by Marie Solari which was exhibited in the St. Louis World's Fair in 1904. It is a large and quite beautiful portrait of Saint Mary Magdalen. We have treasured it in our home for several years. From my NET research she is featured in 5 books but I have not seen them yet: The Artists Blue Book, Who Was Who in American Art, Art Across America, Index of Artists. I am second generation Italian and am glad to have that connection with her townspeople. Good luck in your search. If I find out more I will let you know. Best Regards.
