, Llansilin, Powys, Wales,
Shon Gyfarwydd, who lived in Llanbrynmair was a well-known conjuror.
A farmer in Llansilin parish, who lost several head of cattle, sent or went to Shon Gyfarwydd and asked for information concerning the death of his cattle and for a charm against further loss. Both were obtained and the charm worked so well that the grateful farmer sent a letter to Shon acknowledging the benefit he had derived from him.
This Shon was a great terror to thieves, for he was able to spot them and mark them in such a way that they were known to be culprits. ....
