Elizabeth Stuart (d.1867), Lady Stuart de Rothesay, and Her Daughters, Charlotte (1817–1861) (Later Countess Canning), and Louisa (1818–1891) (Later Marchioness of Waterford)

Hayter's 1830 portrait of Lady Stuart de Rothesay with her daughters Charlotte and Louisa is a variant or companion piece to the double portrait of the girls alone. The inclusion of the mother transforms a children's portrait into a dynastic family group of the type that Reynolds had established as the grandest form of English portraiture. Lady Stuart was the wife of the diplomat Baron Stuart de Rothesay; her daughters were then aged about thirteen and twelve, on the threshold of the social world they would inhabit as Countess Canning and Marchioness of Waterford respectively.

The three-figure composition places the mother at center with daughters flanking, the conventional pyramidal grouping of English family portraiture. Hayter differentiates the women by age and role — the mother's more formal bearing contrasting with the girls' adolescent informality. The handling throughout is competent and warm.
