Although I am replying 8 years later. My grandfather and his sister were from Kocurow in the L'viv oblast. Very near Bibrka in Ukraine. Kocurow to my knowledge is today known as Kotsuriv. We may have some common lineage. Grandfather born 1892 came over in 1907. His name Michael Gula. His sister was Ksenka, later Americanized to Xenia. Feel free to contact me. I'd be happy to share info and perhaps get a bit farther with my own quest.
