Mr Valter Valenčič from Koper kindly provided us with information about the first known mention of the Javorje village. He was given permission to view written materials at the Institute of History of the Slovenian Academy of Sciences and Arts.
The writings were discovered by the historian Prof Milko Kos who published them in Volume 12 of the “Izvestja muzejskega društva za Kranjsko” publication of the museum society, issued in 1902. There it says:
A notarial deed from Cividale del Friuli, dated 5 May 1391, states as follows:
“Jurij from Arson” declared in his will, among others, that his daughter Pyrina would inherit 150 marks as a dowry and for her ‘nuptial dress’ which would be provided from several estates, including the one in “Javorje near Podgrad (im dorf Jaweriach pey Newnhaus)”.
A notarial deed from Gorizia, dated 19 June 1405, again stated the name of the Javorje village in relation to the abovementioned inheritance, namely “Lawriach bey dem Newnhaus”.
