Hello, I am trying to find more information about my grandfather, Ferdinand Linke, who, from the only information that I can find, was born in Warschau on the 19 October 1870. His parents were Ernst Linke and Anna Hoffman. He married my grandmother Sofie(a) Ridinger (Riedinger) in Annopol in 1896. At some point he moved to the Black Sea region. That is all of the information that I have about him relating to Poland and any help at all would be greatly appreciated.
