Hi
Using the Norfolk Record Office catalogue, NROCAT, to see if there is a will, and for references
Dyball, Thomas, of Scottow
ANW, will register, 1812-1813, (1812) fo. 34, no. 25
On the FamilySearch catalogue
Place - England, Norfolk
That brings up a long list of categories. Select Probate records (21 of them)
From the probate records, click on
Wills and administrations, 1469-1857
Author: Church of England. Archdeaconry of Norwich
There are two pages of films, we need the second page
And on that, the film we want is
Regd. copy wills, v. 129 1812-1813
Click on camera icon, and start browsing!
We need folio 34 and as it the will is proved in 1812, it's going to be early on in the film.
Image 39 has folio 34, but T Dyball isn't on that page, and we find him on the next page, as you have seen.
Helpfully the wills are numbered, and his is no. 25, as per the NROCAT result.
You can also see wills for the Norwich Consistory Court at home, but not the Archdeaconry of Norfolk (barring a few films)
I should also say that Norfolk wills, 1800-1857, are on Norfolk Sources
http://www.norfolksources.norfolk.gov.uk/DserveNS/Though Thomas Dyball isn't showing! He ought to be there somewhere? A bonus is that you can see Archdeaconry of Norfolk wills proved from 1800-57 on there.
