There was an abrupt end to Lewis Carrol's relationship to the Liddell family (and their little girl "Alice") in 1863, which lends support to his pedo leanings.  He was also fond of photographing NAKED little girls.  By today's standards, that makes him a closet pedo, which might also explain why he refused to become a priest in the anglican church...feeling too sinful.  I'm glad he refrained from that profession.
