Hi

I am an accountant and some 25 to 30 years ago we used to prepare accounts for a Count "Tony" de Lucovic, who was a genuine count who had a farm in Llanederyn in Cardiff. His full name included Antonio. Back in the early 80's he was in his late 70's and I do not see his name in the telephone book any more. Following up on him through Cardiff links might help you
All the best
