An remark of a French language website of October 2014 ( http://www.noblesseetroya...n-wittgenstein-berleburg/
"...What is difficult to understand in this case is that the Crown Prince had been engaged to a girl who did not belong to the nobility well as excellent family. Elvire Pasté de Rochefort, who has since married Christophe Clamageran, is the daughter of Helen Rodocanachi, colonel of the Air Force, divorced Hervé Pasté Rochefort since died. The Pasté de Rochefort are a middle class family. Helen Rodocanachi is the daughter of Mrs. André Rodocanachi, born Helena Liencourt, and the sister of Pierre Rodocanachi husband of Princess Armande de Polignac, and the half-sister of Josselin, Duke of Rohan.
The engagement was broken so that the marriage in Paris was canceled, apparently for financial reasons related to the marriage contract.
However this girl was not to meet the criteria which were stipulated in the will of the deceased father of Prince Richard Prince, a testament to which we do not really know much apparently (we talked about the need for a noble wife and Protestant). Prince Richard having only one son, his nearest heir of a dynastic point of view seems to be after the son, his own brother, Prince Robin, born in 1938 and seems to have made two successive marriages morganatic (in terms of mediated families), the first in 1970 with a girl from the Swedish nobility Birgitta af Klercker, whom he divorced in 1979, and the second in Paris with Marie-Christine Heftler-Louiche. The first wife remarried to Olivier Fouret and the second, from a family of industrialists, was divorced from Jean-François Malle died today. First marriage came a son Sebastian prince born in 1971 who married Julie Toussaint, daughter of Philippe Toussaint and Barbara Pozzo di Borgo, daughter of Count Pozzo di Borgo François (son of the fifth Duke) and Tatiana Poliakoff-Baidaroff (now deceased actress Odile Versois, among other sister Marina Vlady). They have three children, a son Prince Ferdinand was born in 2004, a daughter born princess Stella in 2006 and another son Philipp was born in 2011. Prince Prince Robin also has a daughter married Natascha Eugenio Litta Modignani, high Italian nobility, and a daughter Marie, Mrs. Olivier Le Maire
After them come the princes of Sayn-Wittgenstein-Hohenstein. The head of this family is the son of the Christian Heinrich, fifth prince, who had first married Beatrix Countess Bismarck-Schönhausen and second wife Dagmar Princess zu Sayn-Wittgenstein-Hohenstein. From his first marriage he had a son, Crown Prince Albrecht, who died shortly before his third birthday in 1953, and from his second marriage a second son Bernhart, born in 1962 and currently sixth and Prince zu Sayn-Wittgenstein-Hohenstein.
He married the Countess Katharina von Podewils-Dürniz (Pomeranian noble family in the fourteenth century), of which he is divorced and they are the parents of Max Wenzel, held Hereditary Prince zu Sayn-Wittgenstein-Hohenstein, born in Prague in 1997 .
There was an error in my reply: Barbara Toussaint daughter of François Pozzo di Borgo is the granddaughter of Joseph 4th Duke and niece of the 5th Duke Charles-André and thus the cousin of the current Duke Reynier, the 6th, Count of Philip, one of the two heroes Intouchables, his twin Alain, Valerie and Alexandra, Mrs. Dominique Dattola...."
