If you go into www.streetmap.co.uk and search under Tarwathie in UK place names it will take you to a dwelling just south of Buckie in Morayshire, Scotland. Neares village is Broadley. This about 36 miles west and a little north from Mormond Hill, Aberdeenshire, which is near Ratven.(not Rathven) So... is this the very farm Sandy mentions?
