I have transcribed the first nine lines to help get you started with your reading.
It won't be the work of a moment to transcribe the whole will, and it's unlikely that anyone will be too keen to take it on.
Also, from a very quick scan through it appears that this William didn't have a wife or children.  (Don't quote me on this.) 
If you have a particular interest in the contents (such as "Does he mention X?" or "What is his relationship to Y?"), then please let us know now.
