This is the result of extensive research which took two years to complete; having started when Phil Hosken was Chairman, and the project had been coordinated by Jacky Casson.

An acknowledgement for all their hard work in tracing Richard Trevithick’s ancestors, namely:

  • Jessie Gregor
  • Terry Simmonds
  • Avril Bond
  • Pat Penhallurick
  • Phil Hosken
  • Jacky Casson

All the research (in paper form) that has been completed is now housed at the Cornwall Family History Society (CFHS) Library in Truro.

  • Anyone can come to the CFHS Library to look at the hard copies or the CFHS have a paid search service.
  • The only paper copy of the tree will also be  housed at the CFHS Library. It is too large to copy being 3 metres long!.

The tree is also available on Ancestry (Public Members Trees) so anyone who has a subscription can view it there.

What we do?

As a Registered Charitable Incorporated Organisation, number 1159639, the Society aims to encourage an interest in Cornwall’s Industrial Heritage through lectures, outings and other meetings and by publishing the results of individual research through its website, journal and other publications.

The Society encourages the sympathetic re-use of redundant industrial buildings along with the statutory protection and preservation of prime examples of all types. It sees recording as an important part of its work where the preservation of a monument is not possible.

The Society maintains close links with numerous public and private bodies having common interests, both at a local and national level, and is affiliated to the Association for Industrial Archaeology and the National Association of Mining History Organisations.

Throughout the year the Society hosts lectures on a range of topics at its centres at King Edward Mine near Camborne and The Public Hall in Liskeard. All lectures are free to members.

The Society’s Annual General Meeting, which includes organised field trips, is also open to all members.
