I am the great grandson of William August Rieck, eldest son of David August Rieck. My grandmother is his youngest daughter, Doris Austin nee Rieck. I am glad to see that there is discussion on the family history. Recently a member of our family completed a somewhat thorough history of the Rieck family. If anybody is interested in this, i will enquire. We are not sure however where Calba, Prussia is or was. If anybody could help with that, that would be great.
