Well I don't know the correct answer and I don't know if anyone could really tell you how it used to be pronounced. The English language has changed so much over the years that if anyone from now travelled back in time to Shakespeare's day they would probably not understand a word of any of his plays. Indeed even today local accents affect the way words are pronounced.
No doubt linguistic scholars could provide a more educated guess but that's what it would be , just a guess.

So I would pick the version you prefer and stick with it. After all no one can really tell you that you are wrong. Just different to how they would pronounce it.
