What is (and what is not) included
The index is designed as a pointer to information on individual Parish Clerks which is not easily accessible by other means. So, for example all references from Ditchfields book and other printed resources that I have found are included, but a list generated by a blanket extraction from the 1881 census index is not.
Additions are always welcome and if the information you supply concerns an ancestor, I will attempt to put you in touch if someone else contacts me about them.
