Marret Frères and Jarry was established by Hyppolite Marret and his brother-in-law, Eugène Jarry, following a dispute with between Hyppolite and his own brother whom he had initially been working with in the family workshop. Jewellers like their father as well as goldsmiths, the name was only officially adopted by their children in 1858 and continued in use until 1879 which allows this piece to be dated to during that time. This piece may well however have been purchased afterwards as the engraved coat-of-arms appears to have been applied later, since it is smaller than the shield designed to receive it. The arms are those of the ducs de Lévis-Mirepoix whose motto reads 'God helps the Second Christian Lévis'. According to family tradition, the Lévis were baptised at the same time as Clovis whose motto was "God Helps the First Christian Baron'. However the design of this coat-of-arms as well as the ducal coronet indicates that the piece probably belonged to Antoine de Lévis-Mirepoix who was the only one at that time to have used the title of Duke, unlike his father Charles-Henri (1849-1915) who used that of Marquess. Antoine de Lévis-Mirepoix, Duke of San Fernando Luis, Duke of Lévis-Mirepoix, Grandee of Spain, Hereditary Marshal of the Faith, was born in the castle of Léran on August, 1st 1884. He studied with the Jesuits, then at the Toulouse College and finally at the Sorbonne where he read philosophy. He joined the army in the First World War, leaving with the title of captain. After the war he started his literary career, writing novels, poems, plays, news reviews and children tales. He was appointed Mayor of Mirepoix during the Second World War and elected to the Academie Française on January 29th 1953. From 1961, he was allowed by decree to use the title of Duke of San Fernando Luis and he accumulated many positions and duties such as President of the Association for the Mutual Assistance of the French Nobility. In 1979, he had to part with his wife's family castle, La Flachère, claiming that the burden of taxes was making it too difficult to keep in the family. He remained alert and active until his death in 1981, still participating as a toreador aged 90 and remaining a loyal monarchist.
