did gene wolfe lose his parents at an early age.  on his blog william gibson writes


Gene Wolfe once said that being an only child whose parents are dead is like being the sole survivor of drowned Atlantis. There was a whole civilization there, an entire continent, but it's gone. And you alone remember. That's my story too, my father having died when I was six, my mother when I was eighteen. Brian Aldiss believes that if you look at the life of any novelist, you'll find an early traumatic break, and mine seems no exception. 

Does anyone know where this is form or who he is talking about?
