Edward de Vere and William Shakespeare are two quite different people who lived in more or less the same place at approximately the same time. Even if he wrote everything credited to Shakespeare (and all the evidence there is on the subject, and there is quite a lot, says he didn't and Shakespeare did), he still would have been a different person from William Shakespeare. Edward de Vere is not Shakespeare in the same way that Nelson Mandela is not Barack Obama.

Pearl de Vere died in 1897.
