Clan Graham has two main families of Scottish clans, the Grahams of Menteith and the Grahams of Montrose. Each have their own tartan patterns. William Graham became the 7th Earl of Menteith in 1610 in what is now Perthshire, Scotland. The Grahams of Montrose had territories in both the Scottish Highlands and Lowlands, and the chief of the clan rose to become the Marquess and later Duke of Montrose.

The Antonine Wall was a turf fortification on stone foundations, built by the Romans across what is now the Central Belt of Scotland, between the Firth of Clyde and the Firth of Forth. Built some twenty years after Hadrian's Wall to the south, and intended to supersede it, while it was garrisoned it was the northernmost frontier barrier of the Roman Empire. It spanned approximately 63 kilometres and was about 3 metres high and 5 metres wide. Lidar scans have been carried out to establish the length of the wall and the Roman distance units used. Security was bolstered by a deep ditch on the northern side. It is thought that there was a wooden palisade on top of the turf. The barrier was the second of two "great walls" created by the Romans in Great Britain in the second century AD. Its ruins are less evident than those of the better-known and longer Hadrian's Wall to the south, primarily because the turf and wood wall has largely weathered away, unlike its stone-built southern predecessor.
