I'm researching my great grandfather Bernhard Karl Hahn (Hahn-2025), born about 1860 in Germany. In 1908, his address was 11 Wall strasse in Dessau. His wife was Elizabeth Ebeke, possibly the daughter of Johann Ebeke. They had 8 children.
My grandfather was Johannes Herman Paul Hahn, b. 27 Dec 1882 in Dessau. He came to America in 1909, with his future wife Dorothea Elisabeth Napp, and they were married in Montreal, QC. In 1916, they moved to Spokane, WA. All of my grandfather's siblings remained in Germany.
Other than ship's records, I've been unable to find information on my great grandfather, or his ancestors.
