Hi - I suggest you order those parish registers at a Family History Centre to view on LDS film, and look at all the entries found for them on the IGI. You can often pick up extra details that way, and it is easier to see families as a whole as you read through them.
Now that you have worked out the will, I hope you will send Brian Lawson the transcript for his wills website?
