I noticed the article in the Daily Post recently and it reminded me about something my father said to me many years ago. He said that his Taid Joseph Hughes carved an inscription on the lintel of the fireplace at the Eagles Hotel in Penmachno
Joseph was a Mason and was living in Penmachno at the time, A few years ago on a visit to Penmachno I popped into the pub and took a photo of the fireplace
