How to cite the National Probate Calendar? The National Probate Calendar for England and Wales is now available on multiple websites (Ancestry.co.uk, Gov.uk, FindMyPast). Not all of these sites are fully name-indexed. I would like to know the best practice for citing an entry such that it can easily be located on any of these websites or (theoretically) on the shelf.

I believe that the only information you need to locate an entry is the year that probate was granted and the name of the deceased.

The calendars were produced annually, listing all grants of probate for the year alphabetically by the name of the deceased. Each calendar is split into multiple volumes, but that split is alphabetical by name.

Personally I normally reference a page, for which I use the year, the first letter of the surname (to determine the correct volume) and the page number.
