I've read that present Lord Rotshild(Baron),whose only son is Nathaniel Rotshild ,is of mixed British -Jewish origin.If I am not wrong,there were some barons Rotschild in Europe,in Austria for example as representatives of a famous dynasty.
My question regards the other British nobles as well.Are there are many of them who have mixed origin(Jewish,Russian.French etc.),besides British?
I mean hereditary peers.
The Rothschild family were all related and were all of Jewish ancestry. They established family branches in Germany, England, Austria and France (and probably other countries as well).
Many of today's British peers do have some Jewish ancestry, given the fact that after the Napoleonic Wars, it was acceptable for impoverished nobility to marry the daughters of wealthy Jews.. thereby saving their landed estates and preserving their status.
In many cases, the wives remained Jewish.. but the children were raised as Protestants.
Hereditary peers with Jewish ancestry include:
George Reginald Oliver Molyneux Herbert, 8th Earl of Carnarvon and his son and heir,
Lord Porchester (b. 1992). The 8th Earl's great grandmother, Almina Wombwell, was the illegitimate daughter of Alfred Charles de Rothschild.
Neil Archibald Primrose, 7th Earl of Rosebery and his son and heir,
Lord Dalmeny. His paternal grandmother was Hannah Rothschild, only child and sole heiress of Mayer de Rothschild. She was the richest woman in England in the 19th century.
Other descendants of Hannah Rothschild, Countess of Rosebery, include
Mary Evelyn Hungerford Crewe-Milnes, Duchess of Roxburghe (divorced from the 9th Duke of Roxburghe - no children), and
Ruth Primrose Wood, Dowager Countess of Halifax.
Charles Edward Peter Neil Wood, 3rd Earl of Halifax, and his son and heir,
Lord Irwin (b. 1977). He is the eldest son of Ruth Primrose Wood, above. His wife and countess is Camilla Younger, former wife of Richard Parker Bowles and ex-sister-in-law of HRH The Duchess of Cornwall.
Simon Charles Henry Rufus Isaacs, 4th Marquess of Reading, and his son and heir,
Viscount Erleigh (b. 1986). His ancestor Rufus Daniel Isaacs was the only British Jew ever elevated to a marquessate.
Charles Edgar Samuel Montagu, 5th Baron Swaythling. Born in 1954, he is the descendant of Samuel Montagu, 1st Baron (born Montagu Samuel). It is not clear if there is an heir to this title.
Peter Robert Henry Mond, 4th Baron Melchett. Born in 1948, he is the descendant of Alfred Mond, 1st Baron. There is no heir to this title, which will become extinct upon his death.
Rupert Harry Bernard Nathan, 3rd Baron Nathan, and his son and heir,
The Honourable Alasdair Harry Nathan (b. 1999). His ancestor was Harry Louis Nathan, 1st Baron.
Christopher Haden-Guest, 5th Baron Haden-Guest (b. 1948). His ancestor was Leslie Haden-Guest, 1st Baron, who converted to Judaism before his 2nd marriage to Muriel Goldsmid Carmel. The 1st Baron later renounced the religion and his son Peter (4th Baron) was an Atheist, but the ancestry remains through Muriel's family.
The 5th Baron is married to actress
Jamie Lee Curtis, who is officially Lady Haden-Guest. They have 2 adopted children, a son and a daughter, although neither can inherit the barony. Adopted children are barred from inheriting British titles, but are given courtesy titles.
The current heir of Haden-Guest is the 5th Baron's younger brother,
The Honourable Nicholas Haden-Guest (b. 1955), who is apparently unmarried.
