John Robertson (1750 to before1818), William Robertson (1753 to 1831) and James Robertson (1761 to before 1818) were successful merchant brothers in Glasgow. The marriage in 1787 of Thomas Sweet (1758 to 1848) and Catherine Robertson (1770 to 1832), daughter of John, linked these two families. Interestingly, one of their their sons, George Sweet,(1790 to 1847) married another Catherine Robertson (1795 to 1880) in 1818, she was the daughter of James Robertson. The family tree chart below shows these links together with William Copland’s position in the family, with whom Thomas had a partnership in Glasgow.
