Eileen in Primrose Yellow (1926). John Lavery (Irish 1856-1941). Oil on canvas. Ulster Museum.Eileen (later Lady Sempill, 1890-1935) was Lavery’s daughter from his first marriage, and she appeared in a number of his paintings. In this painting, Eileen is elegantly posed but there is a sense of warmth and intimacy that differentiates this work from society portraits.
