The point where Lyon enters Tay near the eastern end of Drummond Hill is Rinn Lìomhunn, Point of Lyon. During the summer of 1640 the Earl of Argyll was engaged under the Scottish Parliament in reducing the clans of the North who were against the Covenanters. He had some sort of encounter with the Earl of Atholl near this spot, and seizing him by treachery, as is alleged, sent him prisoner to Stirling. It was somewhat later that Argyll burned the House of Airlie in Angus. Both events are referred to by Iain Lom in his poem on the battle of Ardrennich, near Inveraray, where the Atholl men defeated the Campbells:--

B'olc a b'fhiach do Dhiùc Atholl
Dhol an coinne riut  Eardsaidh;
An déidh latha Rinn Lìomhunn
Thug sibh ìocshlaint mar earlais;
Mheall sibh null thar an abhainn
Marcus Atholl 's a bhràthair;
Chuir sibh an làimh an toll-bùth iad,
Is loisg sibh dùthaich Iarla Iarlaidh.

High up on the south-east side of Drummond Hill there was a small farm of about 28 acres called Ruigh a' Bhaird, the Bard's Slope, a name which suggests that this was the patrimony of the bard attached to the house of Bealach or Taymouth. The prehistoric fort Dun Mac Tuathail is on a spur of the hill looking due east.

Comrie, near the junction of Lyon and Keltney Burn, is Cuimrigh, pronounced exactly the same as Cuimrigh, Comrie, in Strathearn, both being the dative-locative of  comrach, a confluence, though they might be explained as from Welsh  cymerau, the plural of  cymer, a confluence, taken over into Gaelic.

On the left bank of Lyon by the roadside west of Tirinie is a wood called Coille na Calach, the wood of the damp meadow.  Cail, genitive  calach, fem., occurs also in a' Chail Fhinn, the white (or fair) meadow on the south side of Loch Tay (dative case); there are also Cail Bhruar, Bruar Meadow, and Cail Mhinn, Calvin, kid's meadow, near Struan. In Ross-shire we have Cail Fhraochaidh, correctly anglicised as Heathfield, in Kilmuir Easter parish.

Above Coille na Calach is Tom an t-Seogail, rye-hillock, on the farm of Tulach a' Bhile, hill of the brae-edge. On Tom an t-Seogail, as I was told by Mr Alexander Campbell of Borland, the chiefs of old used to meet in council.

This brings us to the pleasant spot of Cois a' Bhile, Coshieville, meaning "near the brae-edge", an idiomatic use of  cois or  an cois, seen for instance in "cois na tuinne" "hard by the wave". Coshieville has an inn and once had a famous market on August 9 (old style), known as Féill Mo-Choid. There is another Cois a' Bhile, Coshieville, at Grandtully, Strath Tay, a snug little hamlet nestling under a brae-edge.
