The Huckleberry Finn quote is just for fun - & it goes without saying that it's historically incorrect (that's part of its humor), but I'll say it anyway.
And as for the many misspellings - as anyone who has read Twain knows, authentic dialect is one of his charms and the spelling is reproduced exactly from the book.

If you're interested in another novelist's take on Henry VIII, Jane Austen also wrote about him in her juvenilia 'History of England' -

It would be an affront to my Readers were I to suppose that they were not as well acquainted with the particulars of the King's reign as I am myself.  It will therefore be saving them the task of reading again what they have read before, & myself the trouble of writing what I do not perfectly recollect, by giving only a slight sketch of the principle Events which marked his reign.  Among these may be ranked Cardinal Wolsey's telling the father Abbott of Leicester Abbey that 'he was come to lay his bones among them,' the reformation in Religion, & the King's riding through the streets of London with Anna Bullen.  It is however but Justice, & my Duty to declare that this amiable Woman was entirely innocent of the Crimes with which she was accused, of which her Beauty, her Elegance, & her Sprightliness were sufficient proofs, not to mention her solemn protestations of Innocence, the weakness of the Charges against her, & the King's Character; all of which add some confirmation, tho' perhaps but slight ones when in comparison with those before alleged in her favour.  Tho' I do not profess giving many dates, yet as I think it proper to give some & shall of course make choice of those which it is most necessary for the Reader to know, I think it right to inform him that her letter to the King was dated on the 6th of May.  The Crimes & Cruelties of this Prince, were too numerous to be mentioned, (as this history I trust has fully shewn) & nothing can be said in his vindication, but that his abolishing Religious Houses & leaving them to the ruinous depredations of time has been of infinite use to the landscape of England in general, which probably was a principle motive for his doing it, since otherwise why should a Man who was of no Religion himself be at so much trouble to abolish one which had for ages been established in the Kingdom.  His Majesty's 5th wife was the Duke of Norfolk's Neice who, tho' universally aquitted of the crimes for which she was beheaded, has been by many people supposed to have led an abandoned Life before her Marriage--of this however I have many doubts, since she was a relation of that noble Duke of Norfolk who was so warm in the Queen of Scotland's cause, & who at last fell a victim to it.  The Kings last wife contrived to survive him, but with difficulty effected it.  He was succeeded by his only son Edward.
And yes, Austen's spelling is entirely her own!
