The image above is a copy of the photocopy of the page of the original register of burials in Errol burying ground, in division number 184, which belongs to "Peter Matthew, Esq. of Gourdiehill", the document was supplied to Peter Symon by Sam Bisset, Bereavement Services Admin Assistant, Perth & Kinross Council (tel 01738 446865 ; email@example.com Thanks are due to Peter Symon of Errol for supplying this.
On examination of this document, it is clear that Patrick Matthew's wife is buried in the same plot, but is recorded as Mrs P (Mrs Patrick) Matthews. They spelled the surname Matthew wrong a couple of times on this document as so many people did then and still do today.
Matthew's wife, Christian (or else Agnes) Matthew (nee Nicol) died in October 1859, not in 1857 as recorded by Calman (1912). See the Patrick Matthew blog for details. This means Matthew would have been grieving for his recently deceased wife when Darwin's plagiarising Origin of Species was first published in November 1859. In 1860 the grieving Matthew tried without complete sucess to claim back his rightfull priority.
A recently unearthed (in 2020) letter, dated 1925, written by Matthew's nieghbour,
David Nicoll of the Parish Council Office, confirming the year of Matthew's wife's death, is below left along with an image of Calman (2012) getting the date wrong, below right. Thanks are due to Fiona Ross of the Carse of Gowrie Sustainability Group for sendng me this.
The letter directly below left is typed by David Nicoll of the Parish Council Office, Errol in the Carse of Gowrie.
Matthew is buried in Errol churchyard. The letter was found by Liz Roberston, after finding it in family papers. The letter is dated 1925, to a Mr Lang of St Andrews. This letter confirms the burial record for Errol Churchyard, whch shows Matthew's wife - named in the letter - Agnes (nee Nicol) Mathew was buried in October 1859, and not in 1857 as Calman recored in 1912.
Given that David Nicoll's first-hand account corresponds accurately with the burial records I think we should perhaps favour his first-hand account that Matthew's wife's name was Agnes over Calman's second-hand interview transcription account that her name was Christian. But we cannot be sure. However, what we can be sure about is that Calman did make errors in his telling of the story of Matthew. For example, in his transcription of a letter Darwin sent to Matthew, an error that has been embarrassingly replicated by others (facts here).
Matthew would have been grieiving heavily when Darwin's (1859) Origin of Species was published in the following November. No doubt Mathew was still grieving badly in 1860 when he tried in vain to prove his rightful priority for the theory Darwin stole.
