Robertson was born at
Kelso or
Edinburgh. His father, at one time assistant-secretary of the
Bank of Scotland, was engaged in business at Glasgow; his mother, Juliet Parish, was the daughter of a Hamburg merchant of Scottish extraction. He was educated at
Dalkeith grammar school. Robertson accompanied his father to South America in 1806. He landed at
Montevideo on the day after its occupation by the British forces under
Sir Samuel Auchmuty. On the cession of the city to the
Banda Oriental, he was sent home by his father, but in 1808 sailed on his own account for
Rio de Janeiro, where he was employed as a clerk for three years. Intending to devote himself to study, Robertson entered
Corpus Christi College, Cambridge; but in 1833 he moved to the
Isle of Wight for his health. He was in London in 1834 for business reasons. He died at
Calais on 1 November 1843. His great-nephew was the singer and actor
John Graham Robertson (1859-1940). ==Works==
