Sandra, I have checked the Interactive Atlas of Slovenia on the disk,and came up with no name of town/vilage DUBLE.
There is however a place called DUPLJE, located in Krain region between towns Kranj and Trzic, as someone already mentioned it,earlyer in this in tread.
I also checked in Slovenian telephone book, where a large number of Tezaks are listed living in Ljubljana, Slov.
Have you found any relation connection with Tezaks from St Andraz, Spodnja Stajerska in Slov.the one I knew in my school years?
With many regards,Raymond...
