I'm reading Wide Sargasso Sea for MCC (and can I just say that it is mind-numbingly boring?), and the following was a footnote:
"Lord Byron (1788-1824) and Sir Walter Scott (1771-1832) were English writers of the Romantic tradition. Both wrote and had political visions about the conquest of the Middle East for the British Empire. Confessions of an English Opium Eater was written by Thomas de Quincey (1785-1859). The library of Rhys's childhood home was similarly stocked with English encyclopedias and histories and tales of travel and Empire: Robinson Crusoe, Treasure Island, Gulliver's Travels, The Arabian Nights (SP, pp. 20-21). Rhys's great-grandfather, James Potter Lockhart, was a cousin of Sir Walter Scott's son-in-law and biographer, James Gibson Lockhart." (Bold mine.)
I'm sure you can guess what I thought of right away. Either I'm completely obsessed, or Rowling is overly fond of Jean Rhys.
