Starting in 1732, although the 'Moss trooper' short title was dropped, the enforcement acts were continued by other variously named acts, most of which continued the established descriptive phrase "for preventing theft and rapine upon the northern borders of England", as the first item included. These later acts include the Perpetuation of Various Laws Act 1732 (6 Geo. 2 c. 37), the Universities (Wine Licences) Act 1743 (17 Geo. 2 c. 40), and the Continuance of Acts, 1750 (24 Geo. 2 c. 57), which continued previous acts until 1 September 1757 "and from thence to the end of the then next session of parliament". The Border families can be referred to as clans, as the Scots themselves appear to have used both terms interchangeably until the 19th century. In an Act of the Scottish Parliament of 1587 there is the description of the "Chiftanis and chieffis of all clannis ... duelland in the hielands or bordouris" – thus using the words 'clan' and 'chief' to describe both Highland and Lowland families. The act goes on to list the various Border clans. Later, Sir George MacKenzie of Rosehaugh, the Lord Advocate (Attorney General), writing in 1680 said "By the term 'chief' we call the representative of the family from the word chef or head and in the Irish (Gaelic) with us the chief of the family is called the head of the clan". Thus, the words chief or head, and clan or family, are interchangeable. It is therefore possible to talk of the MacDonald family or the Maxwell clan. The idea that Highlanders should be listed as clans while the Lowlanders are listed as families originated as a 19th-century convention. Other terms were also used to describe the Border families, such as the "Riding Surnames" and the "Graynes" thereof. This can be equated to the system of the Highland Clans and their septs. e.g. Clan Donald and Clan MacDonald of Sleat, can be compared with the Scotts of Buccleuch and the Scotts of Harden and elsewhere. Both Border Graynes and Highland septs however, had the essential feature of patriarchal leadership by the chief of the name, and had territories in which most of their kindred lived. Border families did practice customs similar to those of the Gaels, such as tutorship when an heir who was a minor succeeded to the chiefship, and giving bonds of manrent.
