Morning Barry,

This will be an Administration rather than a Will, and should be found in PROB 6.

The entry comes from "Index of Prerogative Court of Canterbury Administrations 1750-1800" by Anthony Camp. It may be worth your researcher checking this index first, since this was the primary source for the Devon Wills Index.

According to the source information:

Locating the source and acquiring copies: As an aid to locating the original administration document at The National Archives, the month is given in each index entry, and recorded in the 'Reference' column. The entries in the annual Administration Act Books are divided into five groups or 'Seats' and the Devon entries are found in the second group or 'Surrey Seat' (which includes entries for Cornwall, Devon, Dorset, Hampshire, Somerset, Surrey, Sussex and Wiltshire). Within each group or Seat the entries are sub-divided by month and then by the initial letter of the surname. (Because of the complicated way in which the PCC Admon registers are laid out, it may prove necessary for TNA to charge you a search fee to find the item you require, before they copy it for you.)

It may be that you can use the TNA to do the search of PROB 6 for you.

Hope this is helpful.

Best wishes,
