Marquis of Abrantes

Marquess of Abrantes (in Portuguese "Marquês de Abrantes") was a Portuguese title of nobility, granted by a decree issued by King John V of Portugal on 24 June 1718, to Rodrigo Anes de Sá Almeida e Menezes, 3rd Marquess of Fontes and 7th Count of Penaguião.
In that date, Rodrigo's title was changed, by King John V of Portugal, from Marquess of Fontes to Marquess of Abrantes, once he descended, by female line, from the prestigious Counts of Abrantes, an old line already extinct.
Two of the Marchioness of Abrantes had their title upgraded to the duchess rank (only during her lives), when they became the queen's Maid of Honour ("Camareira-Môr"), the highest palatine office for a lady.
