These excerpts, rather selectively mashed together, come from Was Shakespeare a Jew ?, by Ghislain Muller, 2011. The passage Muller quotes about "John Shappere", from page 193 in his book, he calls "The Langrake Proof", written by James Langrake, of Whittlebury, Northants, in 1569.

"There is no history, only fictions of varying degrees of plausibility."
Voltaire, 1694-1778
