I n August last year I received a message on Ancestry.com. A lady called Rhian, who shared my surname, had sent me a link to a recent BBC news story, which I read with mounting interest.
The head office of the Swansea Building Society, the story said, had recently received a postcard postmarked 1903 and originally sent to a girl called Lydia Davies, who had lived at the address. Having mysteriously received the postcard 121 years after it was posted, staff were hoping to trace one of her descendants.
