Hi David, Following explanations from the Oxford Companion to Local and Family History and 'Ancestral Trails' HERITOR A Scottish term for the landowners in each parish, who until 1845 were responsible for the local poor and until 1925 for the maintenance of the church, manse and school. Valuations made of parishes (mainly in the 19th century), known as heritors' records, are kept at the Scottish Record Office. FEUAR Scottish property was subject to feudal systems of tenure and held ultimately by the Crown. A vassal of the Crown received a grant (or feu) of land for a period of time in return for military or agricultural services. Vassals could in turn sub-feu an estate or part of it to others. A grant was recorded in a deed known as a feu charter or feu disposition. Services were later commuted to a monetary sum (a grassum) and annual payments (feu duty), that were only abolished this century. (Although Feuar is not defined in this statement, I assume the Vassal was the Feuar). TACK A statute of 1854 provided for all land in Scotland to be valued annually. Land was leased to tenants by a document known as a TACK (these sometimes survive in estate papers). That's the best I can do from documents I have here. No doubt some other lister may be able to expand on them. Best regards - Mike Simpson, Penrith, NSW, Australia Email: agene@bigfoot.com HomePage: http://www.bigfoot.com/~agene
