Although The National Archives (TNA) in London has published digitized copies of all Prerogative Court of Canterbury (PCC) wills on their website, a difficulty remains in that the movement of emigrants between two continents and within their chosen destination--coupled with a wide variation in spelling--can obscure their true identity and place of residence. Dr. David Dobson has written this is a completely revised and comprehensive edition of his book "American Wills & Administrations in the Prerogative Court of Canterbury, 1610-1857," not only to bring within one compass the accessible resources of the PCC (including references to all Canadian wills proved in London up to 1857) but to correct some minor (and a few more serious) errors in transcription. The revised guide also includes the location reference needed by TNA to identify and transmit a copy of any will you may wish to order.
