Introduction

boundaries. See Map 10 which is intended to show the boundaries of c. 1825; sources are given in the descriptions. Marches on high ground were often ill-defined, and have always been liable to varying interpretation; but estate boundaries, often confirmed in the later nineteenth century, are more reliable than the old divisions between farms.

areas. Acreages are given from an early source when one is available (converted to Imperial measure), and from measurements made from the Ordnance map according to the boundaries of c. 1825 (see above). The OS areas do not include fresh-water lochs or the inter-tidal zone.

dates of occupation. No dates before 1755 are given for the occupation of particular settlements because Roy's Scotland 1747–1755 was the first map that was sufficiently accurate to enable individual settlements to be identified.

population. The two figures separated by an oblique stroke are respectively the number of occupied houses, and the number of people resident in these houses, at a particular date.

ownership and conveyances. The ownership of the properties that were not included in nineteenth-century Ardtornish (groups V–XI) is dealt with in slightly less detail than that of the first four groups.
