Dear Archive Team,

I am conducting historical research into the General Post Office's
involvement in Guglielmo Marconi's wireless demonstrations in South Wales
during 1897.

Post Office Ltd has advised that your archive is the most likely repository
for surviving historic GPO records relating to this period.

I would be grateful if you could search for any records relating to:

   - Great House Farm, Llandough, near Penarth, Cardiff (not Great House
   Farm, Llandough near Cowbridge).
   - Llandough, Penarth, Lavernock and the surrounding wireless
   demonstration sites.
   - Guglielmo Marconi's 1897 demonstrations.
   - GPO Telegraph or Engineering Department records concerning these
   demonstrations.
   - Correspondence, reports, notebooks, diaries, staff lists, expense
   claims, photographs or plans relating to engineers or officials present.
   - Any references to Mr Williams of Great House Farm, Llandough, who
   family history suggests assisted Marconi before, during or after his stay
   at the property.

If records relating specifically to Mr Williams cannot be located, I would
also appreciate details of any records identifying GPO personnel, visitors
or local residents connected with the demonstrations, as these may help
establish the historical context.

If another archive holds any of these records, I would be grateful if you
could advise where I should direct my enquiry.

Mr Williams of Great House Farm was my great grandad. I am trying to
ascertain if the Mr Williams post office worker, mentioned helping Marconi
in the article, was the same man as my great grandfather. I am also looking
for any more connections between my family, my former home and Marconi and
the radio experiments at lavernock point. Which I understand were already
underway before Marconi arrived to South Wales.

Thank you for your time and assistance. I look forward to your response.

Kind regards,
