My name is Sonja Samulowitz. I live in Frankfurt am Main, Germany. I have numerous ancestors with the name Gutzmer. The family originally came from Eastern Pomerania, which belonged back then to Germany. Now it belongs to Poland. "Gutzmer" is not a German, but a slavic family name. My ancestors came from Bütow, a small town in Eastern Pomerania now called Bytów. Many family members emigrated to North America in the 19 century, the rest went to west Germany after the Second World War.
I hope I could help you
