COPY LETTER: Miss Lucy Williams, 30 Newry St. Holyhead to [Mr. Rex Wailes] thanking him for his paper on tide mills and sending him a rough map of the Strait which shows both Felin Wen and Felin Heli and a photograph of Felin Wen (both lost). Felin Heli is no longer standing but part of the dams and culvert remain and the miller's cottage is still lived in. Nearby is an oat drying kiln originally connected to a house called Ty Mawr on which the railway now runs. Rough sketch map of Felin Heli. Flin Wen is near Llanfair-yn-Newbwll church and was used until about 1870.
