Subject: RE: Freedom of Information / Historical Records Request - Mr. Williams, Cardiff Post Office Engineering Department, 1897 Marconi Lavernock Experiments From: Glamro / Swyddfa Cofnodion Morgannwg Direction: received Date: Wed, 22 Jul 2026 12:44 UTC Institution: Glamorgan Archives Refs: none Archive id: gm-19f89db67d0404c4 ------------------------------------------------------------ 2026/3194 Dear Mr Buckler. Thank you for your email. I have searched our catalogue and I can confirm that Glamorgan Archives does not hold any records relating to engineering activities at Cardiff Post Office, nor to Marconi’s experiments at Lavernock Point, or any material concerning connections between the Post Office’s engineering team / Mr Williams and these events. I’m sorry that I failed to clarify this fully in my previous email.

I appreciate your clarification that Glamorgan Archives does not hold records of past Post Office employees. However, my request was broader than personnel records alone. I was also seeking any historical records held by Glamorgan Archives relating to: * Cardiff Post Office / General Post Office engineering activities around 1897; * the Marconi wireless telegraphy experiments at Lavernock Point and tests to Flat Holm; * correspondence, reports, photographs, deposited collections or other references mentioning the Cardiff engineering team or “Mr Williams” in connection with these events. Could you please confirm whether Glamorgan Archives has searched its catalogues or collections for these broader categories of records, rather than only employee records? If no relevant records are held, I would be grateful for confirmation of the searches undertaken and any catalogue references checked, so that I can direct my research appropriately. Thank you for your assistance.

Thank you for your email, received into our postal system on 16 July 2026. Glamorgan Archives does not hold records of past employees of the Post Office. We suggest that you contact the Postal Museum and Archives for further information on your grandfather’s time working at Cardiff Post Office in 1897.

Dear Information Rights / Archives Team, I am writing to request information under the Freedom of Information Act 2000 (or equivalent records access) regarding my grandfather, Mr. Williams, who worked in the engineering department of the Cardiff Post Office / General Post Office around 1897. Specifically, I seek any records, personnel files, correspondence, reports, or mentions confirming his involvement in Guglielmo Marconi’s wireless telegraphy experiments at Lavernock Point (including erecting the 120-foot pole and related tests to Flat Holm). This relates to contemporary newspaper reports from May 1897. Please provide: * Any personnel or service records for Mr. Williams in the Cardiff engineering department circa 1897. * Documents referencing "Mr. Williams" in connection with Marconi’s demonstrations. * Any other relevant historical files from the GPO telegraph/engineering teams. My full name: Sion Buckler Address: [address redacted], Dinas Powys, Vale of Glamorgan, [postcode redacted][map link redacted] Contact: [email redacted]<[email redacted]> Relationship: Great Grandson I am ultimately seeking any record about my great grandfather Mr Williams of Great House Farm, Llandough, Cardiff (formerly Vale of Glamorgan). Not to be confused with Great House Farm, Llandough, Cowbridge, Vale of Glamorgan. And his role in the Marconi experiment. And before and after Marconis stay with our family in our home in 1897. I am happy to provide further identification if required. Thank you for your assistance.
