One of a set of four small portraits on copper of two of the sons of George, Duke of Brunswick-Lüneburg-Calenburg and Anne Eleonore of Hesse-Darmstadt and their wives (RCINs 401390-3). They are first recorded in the Privy Chamber at Kensington Palace in 1818, without attribution or identification, with ‘curious’ added as a remark.

Éléonore Desmier d’Olbreuse, born into French nobility, was the mother-in-law of George I of England. Her daughter, Sophia Dorothea of Celle, married George Ludwig, Elector of Hanover, who became George I of England in 1714; thus she was the maternal grandmother to George II. She is dressed in the Grand habit, formal court attire worn across much of Europe in the 17th and 18th centuries, with a blue, ermine-lined cloak.
 
The portraits are attributed to Jean Michelin, whose miniatures of some of the ancestors of the Hanoverian monarchs are in the Royal Collection. The artist is said to have been born in Langres, France, and died in Jersey. He became a member of the Académie Royale in 1668 and worked for the Hanoverian court from 1668 until 1686.
