Mr Theroff is correct; it seems that the spelling of "Versegh" in Richard's original posting was just a typographical error.
The late Mrs de Márffy von Versegh was married on 30 June 1953 to László DE MÁRFFY VON VERSEGH (20 XI 1928 - 28 VII 2008), the son of Elemér DE MÁRFFY VON VERSEGH (31 III 1898 - 22 X 1976) and his wife (married 8 XII 1927), Countess Clara SZÉCHÉNYI DE SÁRVÁR-FELSÖVIDÉK (12 IX 1906 - 26 IX 1930).
