Thank you for responding to my posting. My Vouk ancestors hail from Zuzemberk, Slovenia. Through the years the current country of Slovenia has been governed or ruled by several different countries one ofthem being Austria. My Vouk relatives migrated to the U.S. in the late 1800's. To date, however, none of my research has turned up a Felix Vouk. The surname is not all that common and it is difficult locating sources. Good luck in your hunting, If I come across a Felix Vouk in my research, I will forward the information to you.
