Most of the Archdeaconry of Cornwall Wills can be found on FamilySearch. If you don't already have one you will need to create a new account for yourself for FamilySearch. It is quite easy and it is Free!
It is best to Login in to FamilySearch first and then use the following link which will open another window to the Wills page:-
www.familysearch.org/search/catalog/329778?availability=Family%20History%20LibraryThere are three pages involved in the index and you can switch between them using the 'Page' box at the bottom of the first screen. Don't bother with the first page - go straight to the second and then scroll down past all the Administrations until you come to 'Wills, surnames beginning with A'. This is the start of all the actual Wills.
As an example:-
Wills, surnames beginning with B (nos. 1-194), 1601-1608.
This example is basically what all the links will look like although some will have a little more more to deal with like this next one:-
Wills, surnames beginning with C (nos. 5309-5618), 1847-1857; Wills, surnames beginning with D (nos. 1-226), 1601-1622.
This one gives the last of the Wills for surnames beginning with 'C' and then the first part of those beginning with 'D'. It can get a little confusing at times but I am sure you will work it out.
Now, to use these indexes you will need to have an idea of what you are looking for. (You could just scroll through them all but that is far too much work!!) The best idea is to gather the details of the Wills you want to look at. To do this you can use the Kresen Kernow site:-
kresenkernow.org/No login required for this so just click the link and it will take you to the home page. I think the easiest way to go about this would be to have a list of Parishes of interest. St Just is certainly one but you may need to look at others such as Morvah, St Buryan, Sancreed etc.
On the Kresen Kernow home page under the top banner you will see 'Explore Our Collections'. In the search box below type in the following:-
AP/c (parish name) (for Parishes that begin 'St' just ignore that and type the rest - e.g. instead of St Just just type 'Just'. So for St Just type
AP/c just, for Sancreed you would type AP/c sancreed and so on.
AP/ is the prefix for the Wills and C is the first letter of the surname you want which in this case is 'Casley'.
You will need to scroll through the list of entries individually because they are not necessarily in order. What you need to take note of is the CRO Reference Number and the Year. As an example:_
Reference number: AP/C/5
Will of John Cock of St Just in Penwith
Date: 1601
You need to note the Reference Number which in this case is AP/C/5 and the Year (1601) as well as the name of the testator and the parish. Create a list of all of these for each Parish of interest and then go to the Wills Page.
Using one of the examples from above:-
To find the Will of John Cock as listed above you would need to find:-
Wills, surnames beginning with C (nos. 1-397), 1601-1617.This is the listing for surnames beginning with 'C' with reference numbers between 1 and 397 for the years 1601-397.
Once you have selected the correct link for the Will(s) you want to search for simply click on the Camera Icon at the right. This will take you to the first of the images in that set and from there you just make your way through until you find the first page of the Will you want.
NOTE - a great percentage of the Wills have the reference number written on them. It is usually written in pencil at the bottom of the page but sometimes it can be found at the side. Not all pages for each Will necessarily has this number written but by checking images either side you will soon know if you have all pages for a particular Will. (The pages of the Wills are rarely in proper order either so make sure you do check the images)
Images can be downloaded by clicking on the 'download' button at the right of the top toolbar.
If you have any problems or it is a little confusing just send me a note and I will see if I can help you through it. After the first couple of times it does become easier.
