Oh thank you! In the excitement of your response, I have forgotten how to increase the resolution using my programme (its been a while), and have also managed to mess up the original doc by saving without changing the name of the bit cut out. Fortunately it's not too badly damaged, and I'll give it another go and post when done. It might take a day though!
The testament is not in good shape, and the bit where John's wife's name is written, elsewhere in the full page of the document, is very difficult to read because the ink has bled. However, it looks just like the name that you think might be Hugh (and it could very well be, could it not, given that I also have a Nicholas gggrandmother?). John's wife's surname is the same as the name of Rozina/Blezina, just below the possible Hugh in the extract.
You're right, I can do better, and will try to get more examples and higher resolution. Just wanted to acknowledge ....
Thank you!
