Charlotte (left) and Sarah were 19 and 21, respectively, when this portrait was painted on the occasion of Sarah’s marriage to the topographer Daniel Lysons.

There was a seemingly insatiable demand for Thomas Lawrence’s portraits representing stylish English society, but he was notoriously slow working. Although this picture was begun in 1801, it still was not finished in 1806 when a friend noted its presence in the artist’s studio.
