The portrait of Margaret Graham, Lady Napier, is by the Dutch/Scottish artist, Adam de Colone (c. 1572-1651). He worked in the London and Edinburgh courts in the early seventeenth century and made various portraits of Scottish nobility. These portraits include two of Margaret Graham, sister of the 1st Marquess of Montrose and wife of the First Lord Napier (c. 1576-1645). She died shortly after the portrait was made, in 1626.
