The Chiefs of Clan Grant descended from Normans who arrived in Scotland during the medieval period, bearing the French name le Grand ('the tall', 'large').

[7] The victory of Robert the Bruce confirmed the Grants in their lands of Strathspey, where they became established Highland chiefs.

Her family had partially owned it since 1180, when the Crown gave Kinveachy (approximately ten miles southwest of Castle Grant) to Gille Brigte, Earl of Strathearn.

The Grants of Glenmoriston however were committed Jacobites throughout the period, notably fighting at the Battle of Killiecrankie in July 1689.

[16] Clan Grant provided the bulk of the Williamite force under Sir Thomas Livingstone, that defeated the Jacobites at the Battle of Cromdale in May 1690.

[16] During the Jacobite rising of 1715 the main part of the Clan Grant supported the British Government.

The Grant of Glenmoriston branch also fought as Jacobites at the Battle of Culloden in 1746 under the command of the Duke of Perth.

Eighty-four Grants of Glenmoriston were captured at Culloden and were transported to Barbados, in violation of their terms of surrender, where they were sold as indentured servants.

The "Good Sir James" Grant (Clan Chief from 1773 to 1811) built the town of Grantown-on-Spey for the express purpose of providing for his clansmen to keep them from having to emigrate.

The site includes many memorials to clan members, such as Field Marshal Sir Patrick Grant, GCB GCMG (1804–1895), as well as a mausoleum of the Earls of Seafield.

[25] Visitors came from as far away as Scotland as well as from the Yukon, Montana and Manitoba where Grant descendants settled to take part in events arranged for Lord Strathspey's time in Canada.

The burning hill crest represents "Craig Elachie", the rallying point for the Grants.

When signal fires were lit upon the summit of Craig Elachie, or "The Rock of Alarm", members of the clan would gather there in order to organise for an attack or defence.
