The original, 1611 edition of the King James Bible includes the ‘Apocrypha’. These books are included in the Bible we read from here at home (The Jerusalem Bible). Some books are omitted from these that I think should be included...Enoch, for instance. Jude quotes from Enoch in his short epistle.
I don't know the whole history of it, but I think the Deuterocanonicals were included in every edition of the KJV until 1640.
