Bill, I do not have the Slovenian on line phone directory. You should see a place to enter the last name, Praznik. If you see a place to enter village name, enter Velike Lasce. If you do not see a place to enter a village just use the name Praznik.
Write to Zlatica she may be able to help. Have her enter Praznik and the two villages, Velike Lasce and Racica.
