I am trying to find out birth date and death date for Sarah,she was married to my great-grandfather Benjamin W Koehn sometime between 1878-1887.They had 6 children, David-oct14,1881 died dec1,1881,Ben or Benjamin,died at birth,Helena may21,1883,Katie born aug161884,Susie dec29,1885 and Louis born feb27,1887.After that time Sarah died and was buried at the old Dave Rediger place.The first 2 children who died were buried at the Rediger place. I am fairly sure they married somewhere in Russia ,Prussia or Poland but have not found records to support that. After that he married Susie Rediger-Unruh,they had 7 children.
