This is the name of a character in Charlotte Bronte's novel "Jane Eyre", Miss Rosamond Oliver. Rosamond was the love interest of Jane's cousin, St John Rivers.
Rosamond Clifford, known to history as 'Fair Rosamond', was famed for her beauty and as the mistress of Henry II of England. Some accounts have her murdered by Eleanor of Aquitaine, Henry's vengeful Queen, but she joined a nunnery after the affair and was buried at Godstow Abbey near Oxford. The spelling is sometimes confused due to the use of Latin at the time – Rosamundi – but in English her name should carry the 'o'. Daniel's Renaissance poem 'The Complaint of Rosamond' is inspired by her legend.
