Information wanted on my fathers’ family in Zirovac

I am trying to find my fathers' family. He immagrated to the US in 1913. I would like to know if he had any brothers and sisters. He never talked about them. My fathers' name was:  Rade Suzic  (Suzich), from a village , Zirovac,Cavlovica or Komora, I believe his parish was Zirovanic, DVOR, Municipality. His birth date was: Sept. 1, 1895, I believe he came to the state of Pennsylvania where he had a brother Stevan. I've been told he had a sister in Detroit, Michigan. I also understand his mother's name was: Evisa. same name I was babtized with at St. Sava Orthodox Church in Gary, Indiana. If anyone can help me or if any family members are out there please email me at;  [email protected]  I'm very anxious to meet you. He married in February 10, 1922 to Mary Hasara. Anxiously waiting to hear from you.
