Since no one responded to my request for information on the Vrebac last name, I went to my mother and got a copy of my grandfather Nikola Vrebac's baptismal certificate. His kum was either Pero Peric or Pesic. I believe it is the latter. Nikola was baptized in Bosanska Dubica in 1894. I know this is a long shot, but I thought I would try it as well.

Thanks.
