From the Wikipedia page [1] Cornwall Record Office (CRO), part of Cornwall Council, is situated at Old County Hall in Truro and is the main repository for the historical archives of Cornwall. Cornwall County Council was persuaded by Kenneth Hamilton Jenkin and others to set up Cornwall Record Office in the 1950s. Today its three and a half miles of shelving holds millions of individual historical documents, including deeds, leases, manorial records, parish registers, correspondence and diaries, maps and plans, council records and photographs; many of these relating to mining, fishing, farming and most other aspects of life in Cornwall. The documents range in date from the mid-12th century right up to the 21st century and they comprise an exceptionally valuable resource for local historians
