(and what is not included)
The index is designed as a pointer to information on individual Parish Clerks (and other roles) which is not easily found by other means.
So, for example all references from Ditchfield’s book and other printed resources that I have found are included, but a list generated by a blanket extraction from any of the available published census indexes is not.
Additions are always welcome and if the information you supply concerns an ancestor, please let me know and I will attempt to put you in touch if someone else contacts me about them.
