I don't have any more information on them I'm sorry. I can tell you that the isolation of the island has led to a development of an unusual, patois-like dialect of English described as "a sonorous amalgam of Home Counties lockjaw and 19th century idiom, Afrikaans slang, and Italian". 
 In Wim Wnders' film, 'Wings of Desire', a dying man recollects the things that meant most to him mentions the island. Also, 37 degrees 4 S is a short film about two teenagers who live on the island. 
 I have nothing else of them in popular culture, however, I can tell you that there is one island on the school, St Mary's School, which teaches and serves children from ages 4 to 16. 
 I'm definitely a fan! Is there more you can tell me about that? 
 That is super interesting such a small island has so much influence in popular culture! Do you have another fun fact about that?
