Duke of Cadaval

The Dukes of Cadaval have their origins in Dom Álvaro of Braganza, Lord of Tentúgal, Póvoa, Buarcos and Cadaval, 4th male son of Dom Ferdinand I, 2nd Duke of Braganza. Dom Álvaro married Dona Filipa de Melo, the rich daughter and heir of Rodrigo Afonso de Melo, 1st. Count of Olivença.

A new title: Cadaval-HermèsEdit

When Jaime III Álvares Pereira de Melo, 10th Duke of Cadaval died in 2001, he left four daughters: two from his first (civil) marriage (with Antoinette Louise Schweisguth, ex-wife of René Durrieu, 4th Baron Durrieu), and two others from his second (religious) marriage (with Claudine Marguerite Marianne Tritz). Leadership of the house and its possessions was disputed by the elder daughters of each marriage:

  • Rosalinda Álvares Pereira de Melo (born 1936), elder daughter of the Duke's first (civil) marriage;
  • Diana Álvares Pereira de Melo (born 1978), elder daughter of the Duke's second (religious) marriage.

Duarte Pio, Duke of Braganza, in the de jure capacity of Head of the historical Royal House of Portugal, recognized Diana Álvares Pereira de Melo as 11th Duchess of Cadaval.

However, he also granted to her eldest half-sister, Rosalinda Álvares Pereira de Melo, the new title of Duchess of Cadaval-Hermès, because she is married to Hubert Guerrand-Hermès, the House Hermès heir. Dona Rosalinda also obtained both titles of Marquise of Ferreira and Countess of Tentúgal, historically allocated to the heir of the Duke of Cadaval. But Rosalinda (or her heirs) isn't the designated heir to the Duchy and the person to succeed her younger half sister as Duchess of Cadaval will be choose by the Duke of Braganza at the time of the death of the current Duchess.

There is some controversy about the Hermès title, as effectively it constitutes a new creation since inauguration of the republican regime (in Portugal: the Republic abolished all titles of Portuguese nobility in 1910).
