Margaret Macpherson Grant was a Scottish heiress and philanthropist. Born in Aberlour parish to a local surgeon, she was educated in Hampshire, and was left an only child when her elder brother died in India in 1852. Two years later, she inherited a large fortune from her uncle, Alexander Grant, an Aberlour-born planter and merchant who had become rich in Jamaica.

Aberlour is a village in Moray, Scotland, 12 miles (20 km) south of Elgin on the road to Grantown. The Lour burn is a tributary of the River Spey, and it and the surrounding parish are both named Aberlour, but the name is more commonly used in reference to the village which straddles the stream and flanks the Spey – although the full name of the village is Charlestown of Aberlour.
