Re: VUCKOVICH - living in Pennsylvania
Hello, George -
The VUCKOVIC surname is FAIRLY common in Serbia and can still be found in most ex YU republics today.VULETIC is less common and I could get general info on the surname for you, but specifying places and dates of birth for all surnames would be helpful to anyone who might be able to help you in your research.
