Hi, I've been doing some family research lately and found out that our family surname, a part of which is "Vladovich" is a croatian variation on the name Vladan. Our family migrated to Croatia from Albania in the 16th century after persecution by the Turks - this was when the name was altered (in a manner to what is done when a name is anglosized these days). The name is actually the tribal name of one of the Arbanasi clans, not of Serbian origin.
