Jurij Sigmund Valvasor (ca. 1618-1686/89), a member of the famous Carniolan noble family, from which the polyhistor Janez Vajkard descended, is one of the two Valvasors, of whom the polyhistor laconically wrote that they had emigrated from the country, and omitted their wives and children. Both of them had a morganatic marriage, Jurij Sigmund, as it turned out recently, even twice. Due to his (second) marriage to a peasant girl, his »dishonourable behaviour« and his emigration from Carniola, his relatives got the Land Estates of Carniola to deprive him and his descendants of the Land of Carniola privileges in 1657. Jurij Sigmund then lived on the estate of Count Zrinski in Croatia and for the most part in Carinthia, where he earned his living as a mining expert, and is said to have died in Deutschlandsberg in Styria.
