This miniature is by the same hand as another in the Royal Collection showing François duc de Guise (1854-72) (422113). It may therefore be a copy by William Watson after Sir William Ross. A miniature of this type, forming part of a bracelet set with miniatures of the grandchildren of Louis-Philippe, King of the French, and Queen Marie-Amélie, formerly in the collection of Henri, comte de Paris, was at Christie's, Paris, 14 October 2008 (lot 466), there identified as Princesse Marie-Christine d'Orléans, Infanta of Spain.

Princesse Marie-Christine d'Orléans, Infanta of Spain, third daughter of Antoine, duc de Montpensier, and Luisa Fernanda, daughter of Ferdinand VII of Spain
