My family changed Kolacz to Kowatch.
My great-grandfather was Wojcicek (George) Kolacz, from Poland, possibly the Warsaw area, came to the US before Ellis Island was in service. Settled in Edwardsville, PA. He married Anna Mrozska. They had 7 children. George died April 17, 1920, due to a tragic accident.
Anyone know anything else about their siblings, parents or origins?
