The Marquis of Santa Iria (in Portuguese: Marquês de Santa Iria) was a Portuguese title of nobility created in 1833, during the reign of Queen Maria II, for Dom Luís Roque de Sousa Coutinho Monteiro Paim, who already held the title of Count of Alva.

During the 19th and early 20th centuries, the holders of the title also came to represent, through marriage, several other noble houses, notably those of Alva, Óbidos, Palma and Sabugal.

History

The title was granted on 4 April 1833 by Dom Pedro, who was acting as regent on behalf of his daughter, then a minor. The recipient was the son of the diplomat Dom Vicente Roque José de Sousa Coutinho de Meneses Monteiro Paim, 5th Lord of the entailed estate (morgado) of Alva, who represented the Portuguese Crown in Turin and in Paris, where he became ambassador, and of his second wife, Dona Luísa Inês Isabel de Montboissier Beaufort de Canillac, a native of Auvergne and daughter of the Counts of Canillac. On his father's side, he descended from Dom Rodrigo de Sousa Coutinho Castelo-Branco e Meneses, second son of the 9th Count of Redondo.

He was born in Paris on 1 February 1783, during his father's diplomatic mission, and was given an emergency baptism immediately after birth because his life was thought to be in danger. The formal ceremony took place later at Versailles, with the French king and queen, Louis XVI and Marie Antoinette, as godparents. The christening cape used at the ceremony, made of salmon-coloured silk with gold trimming, is part of the collection on display at the Casa de Santar e Magalhães.

He joined the army in 1799 as a cavalry officer. During the Peninsular War he served under Marshal Beresford, rising to the rank of colonel, and was promoted to brigadier in 1820. Removed from the military governorship of the Algarve in 1828 because of his liberal views, he went into exile and joined the liberal forces in the Azores, where he became military governor of São Miguel Island immediately after its occupation by the troops of the Count of Vila Flor, holding the post until the liberal expedition left for the mainland. He then took part in the landing at Mindelo and, during the Siege of Porto, commanded the liberal cavalry as its inspector and commander-in-chief. After the liberal victory, he served as military governor of the Algarve and of the Court and Estremadura between 1833 and 1834, and in 1836 he joined the Supreme Council of Military Justice. He had sat in the Chamber of Peers since 1826, was alcaide-mor of Rio Maior and ended his military career as a lieutenant-general. He also served as Gentleman of the Bedchamber to Queen Maria II and received several Portuguese and foreign honours, including the Grand Cross of the Order of Our Lady of the Conception of Vila Viçosa, the Order of the Tower and Sword and decorations from Belgium, Saxony and Spain. In Lisbon, the family lived in a palace on Largo de São Pedro de Alcântara.

In 1800 he married his niece, Dona Mariana Vicência de Sousa Holstein (1784–1829), who was born in Turin and died in Paris. She was the daughter of Dom Alexandre de Sousa Holstein and Dona Isabel Juliana de Sousa Coutinho Paim, and the sister of the future 1st Duke of Palmela. The couple had seven children; one of them, Dom Alexandre, an ensign in the light infantry (caçadores), was killed in action on the Lines of Lisbon in September 1833. The line of their eldest son, the 4th Count of Alva, died out in the next generation, so the headship of the family passed to the descendants of their third son, Dom Pedro de Sousa Coutinho Monteiro Paim, a first lieutenant in the Portuguese Navy. His marriage in 1839 to Dona Eugénia Maria de Assis Castelo Branco e Lancastre, 6th Countess of Óbidos and of Sabugal and 7th Countess of Palma, joined these noble inheritances to that of Santa Iria. Along with the house of Óbidos, whose title was hereditary in perpetuity (de juro e herdade) and carried the honours of a royal kinsman (honras de parente), the family also inherited the hereditary office of Chief Bailiff of the Realm (meirinho-mor do Reino).

In 1945, on the death of the last Count of Óbidos, the representation of all these houses passed to his nephew, José Luís de Vasconcelos e Sousa, the son of one of his sisters. Born in Lisbon in 1888, he was the son of Luís de Vasconcelos e Sousa, a fidalgo cavaleiro of the Royal Household, and of Dona Eugénia Maria das Dores de Melo de Assis Mascarenhas, through whose maternal ancestry he was linked to the Mascarenhas and Sousa Coutinho families.

The family archive, comprising documents dating from 1384 to 1908, was bought at public auction in 1995 and is now held by the Torre do Tombo National Archive.

The family's connection with the village of Santar, in the municipality of Nelas, dates from the marriage in 1947 of José Luís de Andrade de Vasconcelos e Sousa to Maria Teresa de Lancastre de Melo, daughter of the 3rd Viscounts of Taveiro and representative of the House of Santar and Magalhães. From 2013, their descendants developed the Santar Vila Jardim project, which linked several of the village's historic gardens and opened them to the public, following a plan by the Spanish landscape architect Fernando Caruncho.
