Biography
Military officer. Son of a Physician in London of the same name.
According to a 19th century volume of correspondence between Mrs. Grant of Laggan and her friends, Leitch "was sent very early into the army, full of romantic prejudices, which led him into boundless profusion and endless errors. With great purity of heart, and uprightness of intention, he very early dissipated his patrimonty, and soon after was so much in debt as to be obliged to sell his commission, about the period when this letter was written [1775, ed.]."1
