A kind, undemanding neighbour and Mrs. Bennet's useful social counterpart.
Lady Lucas is the wife of Sir William Lucas and mother of several children, including Charlotte Lucas. The narration calls her a very good kind of woman and, significantly in the Bennets' social world, not too clever to be a valuable neighbour to Mrs. Bennet.
Her household at Lucas Lodge is intimately connected with the Bennets', and the Lucas daughters join the Bennet sisters at Longbourn to discuss the consequences of the Meryton assembly. Her individual actions and appearance are not yet developed beyond this social place.
The text provides no description of her age, face, hair, complexion, figure, or dress.
She is a stabilising member of the Lucas household and a valuable neighbour to Mrs. Bennet.
