Jules de Lasteyrie du Saillant (1810-1883)

He was born at his family's country estate, Chateau La Grange. He was a grandson of the Marquis de Lafayette and brother-in-law of the political writer Charles de Rémusat. Following his education, Lasteyrie entered the service of Dom Pedro I of Brazil and took part in the expedition which expelled Dom Miguel from Portugal. In 1842, he was elected to the Chamber of Deputies, voting with the Center-Left. In 1848, he was elected to the National Assembly and defended the Duchess d'Orleans that February when she controversially entered the Assembly. He took a hostile attitude towards the Republic and its President, Napoleon III. Owing to his continued opposition, he was banished in 1852 but was included in the amnesty later that year. In 1871, he was elected to the Assembly representing the department of Seine-et-Marne and the following year declined the post of Ambassador to Rome. In 1875, he was appointed a Senator, and while he started his career as a Constitutional Monarchist, he ended it as an advocate of the Republic. In 1846, he married Olivia, daughter of Louis de Rohan-Chabot, the half-Irish aide-de-camp to the Duc d'Orleans (Louis Philippe I), by his wife Isabella Fitzgerald, daughter of the 2nd Earl of Leinster and Lady-in-Waiting to Louis Philippe's wife, Maria.
