Peter, the grandfather, died on 24th March, 1551, but his son Richard died a violent death in a tragic manner in 1565. Peter, the younger and heir apparent, was intent on marrying Jane, the daughter of John Wrey, of Northrussell, but for some reason unexplained his father Richard took a violent dislike to the proposed daughter-in-law, and when his son persisted in desiring to have her as his wife, the father flew into a violent passion and swore that if he took her he would disinherit him of all the lands he could, and would give to him only a younger son's portion, constituting Richard head of the family. Peter remained firm--he was then in London at the Court, and the father at once made ready to leave Newton Ferrers and take his journey to London and disinherit his son if he found that the marriage was still insisted on. But on the eve of his starting, as he was walking in the grounds of Newton Ferrers, he was suddenly fallen upon by two scoundrels named Bartlett and Baseley, who owed him a grudge over some matter that is not mentioned, and they cut his throat. Bartlett and Baseley were apprehended and brought to Launceston before the sheriff, Mr. Trevanion, and were found guilty; but he could not believe that they were revenging some private wrong, and as the matter of dispute between father and son was well known, and it was known as well that Richard was about to disinherit his eldest son, a strong suspicion was entertained by Trevanion that the murder had been committed at the instigation of the son, and he gave the men hopes of a reprieve--if not of a pardon--if they would reveal the name of the man who had urged them to commit this dreadful crime. He behaved, it must be seen, in a most unfair manner, hinting his suspicions to the two wretches and giving them no peace till they declared that they had been set on by Mr. Peter Coryton to murder his father. As Peter Coryton was in town, the two criminals were sent to Newgate to be confronted with him there. Whether he was arrested on the charge of having instigated the murder of his father does not appear, but it is probable. However, if that were the case, his detention was not for long, as both murderers recanted when in London. The following curious deed of "Evidence concerning the murder of Mr. Coryton" is preserved in Pentillie Castle. "To all true Xtian people to whom this present writing shall come, or shall see, hear or read, Sir Richard Champion, Knt., Lord Mayor, and the Aldermen of the City of London send greeting in our Lord God everlasting.
