"A few early charters from the days of King Alexander the Second dealing with the Erskine line occupy the first part of this report, and there are several by the Earls of Mar to their vassals ... The chief interest of this report, however, centres in a series of letters written between the years 1612 and 1625 from London to John, Earl of Mar, by his cousin, Thomas, viscount Fenton, afterwards earl of Kellie."--P. vi.
