The English earldom is today the main non-ducal subsidiary title of the Duke of Richmond.

The current duke's eldest son, named Charles like his father, enjoys it as a courtesy title.

The Earls of March on the Scottish border were descended from Gospatric, Earl of Northumbria, but being soon afterwards deprived of this position he fled to Scotland, where Máel Coluim III, King of Scotland, welcomed him and granted him Dunbar and the adjoining lands.

[3] He was succeeded by his son, also William, who married Anne Douglas-Hamilton, 2nd Countess of Ruglen.

The earldom of March and its two subsidiary titles were inherited by his second cousin once removed Francis Wemyss-Charteris, later the eighth Earl of Wemyss.

He forfeited his title, which was in the Peerage of England, for treason in 1330, but his grandson Roger managed to have it restored eighteen years later.

In the Peerage of England, the next creation of the earldom came when Edward Plantagenet, Duke of Cornwall was made Earl of March in 1479.
