Looking for Jacoby S from Stettin Germany

My husbands grandmother's maiden name was Jacoby. I am trying to find anything about her family. She was Margarete Jacoby and she married Bruno Putziger. They moved to South Africa in the 1940's. Her father was Heymann Jacoby and her mother was Martha Oppel. She had a sister Kate and a brother called Heinz. Heinz was killed in the 1st World war. Kate lived in Florida, USa, married twice but never had children. They originally came from Stettin. Bruno's family was originally from Filhne in Germany, and Bruno and Margarete's children Hans and Gerard were born in Charlottenberg. Anyone who can help me with any info regarding the Putzigers, Oppels or Jacoby's would be much appreciated!
