The sitter is presumably Elizabeth, daughter and co-heiress of Sir Alexander Bannerman, 4th Bart., and his wife Elizabeth Sedgewick. She married, in 1782, Alexander Burnett (1757-1810), second son of Sir Thomas Burnett of Leys and Catherine Ramsay of Balmain, heiress of her brother Sir Alexander Ramsay-Irvine, 6th Bart. Alexander Burnett assumed the arms and name of Ramsay and was created a Baronet in 1806. They had four sons and five daughters.
