p 92 | Mme Alphonse de Rothschild: (wiki). In 1857 Alphonse de Rothschild married a cousin, Leonora "Laure" de Rothschild (1837–1911), the daughter of Lionel de Rothschild (1808–1879) of the English branch of the family. They had four children.
p 92 | Baron Hirsch= Maurice de Hirsch de Gereuth (1831-96), Jewish banker & philanthropist.
p 92 | Charles-Ferdinand, Duc de Berry (1778-1820). He is reported by historians to have been temperamental, moody, selfish & extraordinarily ugly. For several years, he lived with (or married) an English woman named Amy Brown, and they had two daughters. (Some claim there was an official marriage that was annulled by the Pope when the Bourbons returned to power. However, no documentation has been produced to support this.)
The Duc de Berry was assassinated in 1820; a deathbed act was to legitimize his two daughters by Amy Brown and they were adopted by his royal wife. Both daughters later received titles from the Duc the Berry's father--King Charles X.
Two of the Duc's other mistresses were: Eugénie Virginie Oreille (1795–1875): had 2 sons: Charles Louis Auguste Oreille de Carrière (1815–58), who in turn fathered a son Charles (born in 1842), a lyric artist, married but without issue; and Ferdinand Oreille de Carrière (1820-76), who died unmarried.
With Marie Sophie de La Roche (1795–1883), there were 2 sons: Ferdinand de La Roche (1817–1908) and Charles de La Roche (1820-1901). None of these seem like Swann, or even like Swann's grandmother.
p 93 | "..where Monaldeschi was murdered...": (wiki) With the cession to the Papal States of Torre Alfina in 1664, the Monaldeschi ceased to play a part in the politics of Central Italy, though the marchese Gian Rinaldo Monaldeschi was reputed to be the lover of Christina of Sweden. When she discovered that Monaldeschi had betrayed her, she had him assassinated 10 November 1657, at Fontainebleau, where the she was staying. Her version is here.
