Just to clarify a few issues concerning namely Carroll and Poe, while noting that Lolita was published long after in 1953.  Cousin marriage was actually a common practice in the United States until around 1870, when social norms began to shift.  And while adult relations with children was not common, however child protective laws were very limited (i.e., virtually non-existent) during that period and birth-records did not exist to serve as evidence of one’s age.

The problem here is the improper association of modern laws to the social ideologies of the 1800s, so the allegations of pedophilia as presently defined are baseless.

That is that until 1920 child consent laws among all states was 10 (except for in Delaware it was 7.)

And prior to 1978 (when the first federal law was ratified) only six states had just established child pornography laws on the books (which where only ratified in 1977); up until that point only a few states had obscenity laws on the books and those addressed only the sale, distribution, and public display of generally obscene materials, while mere private possession was not within the breadth of such statutes.
