It has been widely rumored that Felix Elston was the natural son of Khitrovo's eldest daughter, Countess Ekaterina Tiesenhausen (a lady-in-waiting to King Frederick William IV of Prussia's sister, Empress Alexandra of Russia) and Prince Augustus of Prussia."@en . . .

"Felix (a common name for illegitimate children) was brought up by Elisabeth Khitrovo (ru), a famous salon-holder who was a daughter of Prince Kutuzov and the mother of Dorothea de Ficquelmont. It has been widely rumored that Felix Elston was the natural son of Khitrovo's eldest daughter, Countess Ekaterina Tiesenhausen (a lady-in-waiting to King Frederick William IV of Prussia's sister, Empress Alexandra of Russia) and Prince Augustus of Prussia. It appears more likely that Felix's parents were Karl Alexander Anselm Freiherr von H\u00FCgel (Regensburg, April 25, 1795 \u2013 Brussels, June 2, 1870) [himself the son of Johann Aloys Josef H\u00FCgel, later 1st Freiherr von H\u00FCgel (Koblenz, November 14, 1753 \u2013 Regensburg, 1826) and wife Anna von Holthof, married in 1787] by Jozefa Gr\u00E4fin Andr\u00E1ssy de Cs\u00EDkszentkir\u00E1ly et Krasznahorka (Ko\u0161ice (Kassa), April 8, 1790 \u2013 1868), a relative of Gyula Andr\u00E1ssy, married (in Ko\u0161ice (Kassa), February 7, 1808) to Mikl\u00F3s Graf Forg\u00E1ch de Ghymes et G\u00E1cs (1784 \u2013 Nagyszal\u00E1nc (Slanec), January 10, 1857), by whom she had three sons, all of whom died unmarried and without any issue. Recent investigations taken by one of his great-granddaughters and an English genealogist practically confirm this late ancestry, not explaining, however, the motives why he didn't use his father's name but Elston, his English nanny's surname."@en . . . .
