Isola Francesca Emily Wilde was named in tribute to Iseult of Ireland from Celtic legend, wife of Mark of Cornwall and lover of the Cornish knight, Sir Tristan. Isola shared the name Francesca with her mother; Emily was the name of her maternal aunt. According to Oscar, Isola lit up their lives like “a golden ray of sunshine dancing about our home.” http://womensmuseumofireland.ie/articles/isola-wilde--2
Isola was Oscar Wilde's youngest sister and only 9 years old when tragedy struck. She was visiting relatives in Edgeworthstown in Longford County, Ireland and became ill. She died in 1867 and was buried in the nearby cemetery; St John’s Graveyard. Oscar was profoundly affected by the loss of his sister and wrote the now famous poem "Requiesvat" in her memory. He carried a lock of her hair in a decorated envelope until the end of his life. http://edgeworthstown.net/blog/blog1.php/isola-wilde-memorial
At some point, the headstone erected by the Wilde family in memory of Isola disappeared from St John’s Graveyard in Edgeworthstown and its location was never discovered. In 2013, the people of the town commissioned a beautiful replacement inscribed with the first stanza of Requiescat. It is situated just inside the gate of St John’s Churchyard.
"Requiescat" Tread lightly, she is near Under the snow, Speak gently, she can hear The daisies grow. All her bright golden hair Tarnished with rust, She that was young and fair Fallen to dust. Lily-like, white as snow, She hardly knew She was a woman, so, Sweetly she grew. Coffin-board, heavy stone Peace, Peace, she cannot hear Lyre or sonnet, All my life’s buried here, Heap earth upon it
