Correction: The name of my grandfather`s mother is not as written " Hertha ", but IDA. MY grandfather`s father was named HERMANN. IDA Jeske`s name at birth was MERTENS. Ida`S and Hermann`s children were August ( my grandfather ) 1926, Hertha 1928, Arthur born in 1930. Ida and Hermann married in Posznan ( Posen )about 1924/25. The place they had lived in poland, leslau (Wloclawek ) must have been nearby a sea or river ( he often told something about their horses to ride at the water ).
