Volume 4, page 131, sitting number 4593.

Gaston d'Orléans was the first son of the duc de Nemours. His full name was Louis Philippe Marie Ferdinand Gaston d'Orléans. He became a military commander and fought in the Spanish-Moroccan War and the War of the Triple Alliance. 

Renouncing all rights to the throne of France, in 1864 he married Isabella of Bragança, daughter and heir of Don Pedro II, in Rio de Janeiro. Their children and issue use the name Orléans-Braganza, and are the claimants to the Brazilian imperial throne. Currently, the dynastic Head of the Imperial House of Brazil is Prince Luiz of Orléans-Braganza, Gaston's great-grandson. Another of his great-grandsons, Duarte Pio, Duke of Braganza, is the current presumptive heir to the throne of Portugal.

The comte d’Eu died on 28 August 1922 at the age of 80, at sea, on board the Massalia, on his way back to Brazil. He was originally buried at Dreux in France but was reburied in 1953 at Petropolis in Brazil.
