Frances Mary Lavinia Polidori, "later" Rossetti, (c. 1801 - 8 April 1886) is noted for her family connections rather than in her own right; in particular, two of her children were co-founders of the Pre-Raphaelite Brotherhood, and another became a famous poet. Frances was the daughter of Italian exile Gaetano Polidori and sister of John Polidori, Lord Byron's physician. Wikipedia
