Charlotte Elizabeth St.John (1830- 1871) was the granddaughter General Frederick St.John and Lady Mary Kerr. She was born in Algiers where her father, Robert William St.John, held the post of Consul General.
This picture is a stipple engraving published by the well-known engraver William Henry Mote after a portrait by society artist John Hayter (1800-1895).
Charlotte is dressed in typical early Victorian style with an off the shoulder neckline and lace bertha (collar).
It was said of her that "she will die unmarried, poor girl" which indeed she did, aged just forty years in 1871.
