Yes Dengler is German. John Dengler fathered Barbara Ann Dengler who was born Aug 1946-1993.She had 3 sisters and 1 brother. Shirley, MaryJane, Katherine, and Richard(died 1960). All lived in Buffalo NY.
I am trying to find out if John Dengler was adopted.According to his birth cert he was born to John and Catherine Kinsler on Sept 14th 1906. But his parents maiden name on his death cert is John Dengler and Mary Abram. Do you have any info for me?
