I don't have much on the Demsar name. This family would be from Sinja Gorica a little southeast of Vrhnika. My Grandma Artac nee Lusina's sister Marija married Franc Sajovic. Frank and Mici had a daughter named Julija b. October 4, 1876 and she married Anton Demsar Sr. They had children named Anton Jr.; Nada m. Savli and had a child named Bernadette Savli; Milena m. Franc Lorencic and had triplets named Carmen, Theodora, Romanca and a son named Tony. I have written to Carmen two times but have gotten no response from them. I have some pictures of the Anton Demsar family on my web page at http://communities.msn.com/genealogy2000
on the Artac/Lusina/Merlak page. My other page is http://genealogy2002.tripod.com
These photos were taken by my dad at the end of World War II.
