Thank you, Jane, for your offer of assitance.

My main interest is the family Oldfield as I have now established that they are indeed part of my early family tree. I have made contact with someone who has undertaken considerable research into this family, and I hope to learn much when we are due to meet next month.
I started off trying to find out more of the Oldfield dynasty by gleaning what I could from the web pages of the many churches which still have Oldfield bells (mostly in Nottinghamshire) and it gave me a good 'feel' as to the standing of their Nottingham bell foundry in the late, sixteenth, seventeenth, and early eighteenth centuries. I also discovered the approximate dates of successive generations of the family. [I can send you my current list of Oldfield bells if you wish. It has no pretensions of being comprehensive, but perhaps a useful start. It reveals a couple of instances where bells seem to have been credited to the "wrong" Oldfield, too.]
I think therefore that I need not, at the moment, take up your kind offer but thank you again for making it.
