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], Vale of
Glamorgan, [postcode redacted] Contact: [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.

Best regards,

Sion Buckler (Ret'd Sergeant)
