Probably Jane Lyttelton, Mrs Sharington II Talbot

British (English) School. Oil painting on canvas, Possibly Jane Lyttelton, Mrs Sharington II Talbot (possibly by the same hand as no.16). A three-quarter length portrait, turned slightly left, in corseted green striped and spotted dress, over which is tied a black coverlet, fastened with a red striped bow, which is mirrored in both sleeves; the dress is embellished with an elaborate lace collar and cuffs. She wears two necklaces, on one of which is strung a ring, and bracelets on both wrists (the chain of that on her left hand extends and attaches itself to her ring). She wears a rose in her hair, and holds a fan in her left hand. Like her husband (if it is he) she wears a braid extending from her left ear. Lacock, Wiltshire
