Kaye Torwood is in Birnam, Little Dunkeld Parish, I have the Memorial Inscriptions for that parish and there are a fair number of stones have Torwwod listed on them. If you go to the old maps web site and put in Perthshire then Birnam and then click to enlarge the map, Torwood is pretty much in the centre although the writing is a little hard to decipher. It is to the south and slightly right of Birnam Cottage. http://www.old-maps.co.uk/oldmaps/large_ind.jsp Hope that this helps, if you want the mentions of Torwood let me know Heather J
