To all on this theme,
I run the environmental education centre in Austerfield and have done an amount of research on this subject.
The murder took place over the evening period as Dyon was returning home from the markets in Doncaster. His brother and nephew had made an abortive attempt to murder him the previous week, but he had failed to go to the market due to ill health. ( trial transcript which i have full copy of)
They had therefore left their guns in the barns at Partridge Hill Farm, a property at the beginning of a series of gateways leading to Brancroft Farm, for the week, returning the following week to lay in wait for his return.
If you use google maps to look for Austerfield, Brancroft still exists to the south east of Doncaster Sheffield Airport runway on the edge of the Finningley Road, with Partridge Hill to the south of the runway. Unfortunately, the tarck with the gateways no longer exists as its under the runway. Dyon House Farm and Dyon cottage have no known ownership link with the Dyon family, but I will check with the 1765 enclosure map to see what land they owned at that period. It is probably more likely that they were named as such as part of a moral tale with a warning for the outcome of greed. The trial transcript indicates the brothers gained wealth from their father and whilst one made more from his wealth the other was profligate and spent his apportioned amount. The death of his brother and some inheritence from it was indicated as the motive in the trial.
I have photos of the two dyon named properties at work and will attach them to another mailing. I also have the parish records for baptisms, marriages and burials as part of a transcription programme i did for the local fhs and will check those. There is not a headstone in the graveyard for this family,as there are a large number of plots without any markers. Although the parish is physically in Yorkshire it is part of the diocese of Southwell and as such its parish records are held in the Nottingham Archives.
