Wales countryside

Wales is a mountainous country that is part of the United Kingdom and the island of Great Britain.



In 1857, Edmund Herondale and his wife Linette moved to Wales and lived near Dolgellau in the shadow of Cadair Idris for years, until their daughter Ella died and son Will disappeared. By 1876, Edmund had gambled their house away and they were forced to move.[1]
