Hi,My grandmother was Gertrude Ida Tetzlaff. When I was a child she corresponded with cousins in Germany. As I remember they lived behind the Iron Curtain. she sent things like coffee but was never sure if it was received by them.Her father and mother made a trip from Wisconsin to Germany about 1886 during which time my grandmother's sister Mathilde was born.I have a photo taken in Berlin of some members of the family but do not know their names. Do you have any cousins in Wisconsin?
