Thanks, Madeleine. I will have a look later. I just remember that the publisher was adamant that it stayed as an i not a u until the next editions. I thought it could just be for an iota ( the well known only difference between the word for fish and Jesus is just an iota ) or even as the old letter for J, Juden, as seen on the crucifix INRI.a nod to Shakespeare's origins and meaning he would not be buried in any Christian grave.i could also be Immured i.e. In the wall..how creepy, maybe the statue is his skeleton covered in plaster..don't want to think about it....Could also refer to In Capite ..everyone receives an equal share of the inheritance or The Boss, directly from the Crown
i also represents the Finger of Yod. A significant astrological configuration in a birth chart..Karmic Destiny, often a Leader.
and then of course we have Io and a headless body in the churchyard..:)

I imagine future researchers will have this problem in reverse. Searching the records will probably turn up millions of Selfies, Texts, Emails and Hacked accounts all for one person.
