Hi
About Benbuy I found this
These notes come from Origines Parochiales Scotić, 1855, vol. ii, part i, pp. 85-90. The northern portion of the MacVicar lands is traversed by the valleys of Glenshira and Glenaray (Fig. 1). Its highest mountain is Benbuy, 2,800 feet above the sea (853 m). All of this area is understood to have once belonged to the MacNaughtons, who accept the MacVicars as a sept (the MacVicars could be descended from a MacNaughton who was a vicar). This section, on page 61, goes on:
In the year 1403, Margaret, the daughter of Gyllecrist, called Macgillegeachin, with the consent of her son and heir, Fynlay Macawaran, resigned to Colin Cambell Lord of Lochaw, her overlord, the sixth part of the lands of Glenserw (Gleann-sěora) and of other lands which heritably belonged to her, and which had formerly belonged to Alexander McNeachden, lord of the same lands.
Angus Macnaghten [13] on page 19 tentatively identifies this Alexander as a Chief of our Clan. This seems to refer to Glen Shira.
In 1596, Archibald, Earl of Argyle, appointed Alexander M’Nauchtan, the son and heir of John Macnauchtan of Dundaraw, keeper of the forest of Benbuy for 19 years, for the yearly payment of Ł80 and on condition that he not keep “oversoumes” in that forest. [p. 64]. There still exist the remains … of the castle of the Macnaughtens on the Důloch … A standing stone on the castle lawn is said to mark the old march between the McIvers and M’Vicars. [p. 65].
A march can mean a boundary; there are no decipherable marks on the stone [Fig. 2] nor any indication when it formed such a boundary. The McIvers are not listed as a sept of the Macnachtan Clan in The Red Banner
