Thanks to you both for your helpful replies. I've just spent a fascinating evening exploring Google Books. It hadn't occurred to me to try that. I was very pleased to see a drawing of the gravestone of Jeremiah Clark, as he is a member of my Clarke family. I'd never heard of yields as being divisions within a parish. Very interesting. I was thinking Burnford was a hamlet, so that has been clarified.
Thanks again for responding.
