We confirm we searched our full catalogue across all centuries for your Marconi/Great House Farm query, found no restricted material applies given the age of the records, and note that relevant items are held at BT Archives.
“it's very unlikely anyone would still be alive and have any personal information that would still be up-to-date”
We confirmed searches covered both catalogued and uncatalogued items using all requested keywords, found no relevant matches for Great House Farm, Llandough or Lavernock, and said items for Penarth or Williams were unrelated or held at BT Archives, which we had not separately checked for digitisation status.
“nothing came up about people who participated to the demonstrations”
The family asks the Postal Museum to confirm whether 1895–1900 was fully searched, to give reference numbers for excluded 'unrelated' catalogue results, to clarify whether uncatalogued material is represented, and whether any related records were restricted or inaccessible.

We found no records mentioning Great House Farm, Llandough, Penarth, Lavernock, or a named Williams connection, and advised that Marconi and GPO wireless telegraphy files are mostly held at BT Archives, suggesting Glamorgan Archives too.
“Almost all the files related to Marconi are held in BT Archives”
We confirmed receipt and said a full reply would follow within 10 working days, noting our archive's opening hours and booking process.
We searched for Great House Farm, Llandough, Lavernock and wireless demonstration keywords and found nothing relevant, confirming that Marconi and Telegraph Department files are all held at BT Archives.
I thanked the archive for its searches, confirmed the Penarth/Llandough/Lavernock location is correct, and asked exactly which terms and collections were covered so I can judge how thorough the search was.
“could you let me know whether the search you carried out included any of the following terms or collections”

I corrected the surname to Williams, not William, and asked for details on exact search methodology, whether catalogued and physical holdings were checked, and whether searches covered private individuals or local hosts connected with Marconi, not just GPO staff.
“He may instead have been the owner/occupier of Great House Farm who assisted Marconi locally”

“aims to respond to your email within 3 working days”
I asked The Postal Museum to search for records relating to Great House Farm, Llandough near Penarth, Marconi's 1897 wireless demonstrations, and any GPO personnel connected to them, including a possible ancestor who may have assisted Marconi.
“family history suggests assisted Marconi before, during or after his stay at the property”
