Please contact me if you have Karas relatives from Tywara Solna, which is now in Poland.  I am Petro Karas' step-daughter Helena Zigabarra.  He married my mother Anna in 1956 in Yonkers, New York. USA.  They are both deceased.   I believe Petro had a niece or sister named Amelia in Poland.   Helena Zigabarra Kosorek
