Further to my earlier email on this subject it has been suggested I post the fellow's name. It is FREDERICK CLAUDIUS JOHN PARKINSON. His father was John P. of the Consular Service and his mother, Frances, the illegitimate daughter of John Thomas Foster, the then husband of Lady Elizabeth Foster,nee Hervey, who later was to become the Duchess of Devonshire upon her friend, Georgiana's death. My thanks to Judy and Rosemary for their help. Nick
