Henry Pelham's Lost Grand Jury Map of Kerry (c.1800): A Newly Found Derivative

The ‘South Division of the County of Kerry’ (GSI FS 1.2.001) is a copy of the southern half of a lost late eighteenth / early nineteenth century map of County Kerry, in southwestern Ireland. Geological annotations on the map are traced to specific episodes (c.1820, 1838 and 1844) in the unofficial geological survey of Ireland conducted by Richard (later Sir Richard) Griffith between 1811 and 1855. The Griffith provenance of the map is part of the evidence used to identify the ‘South Division of the County of Kerry’ as a derivative of the now lost Grand Jury map of Kerry made by the American émigré artist and cartographer Henry Pelham.
