Birmensdorf images 4-52 are indexed as if witnesses were parents, father not listed.
In the Birmensdorf online images, Film #008014302, images 4 through 52 are all indexed correctly.
The father's name is underlined and the mother is not listed. Every entry ignores the father and puts the witnesses as mother and father. Anyone looking for an ancestor during this time using indexing will not find them. I am worried that many people who do not even exist will have their work done and be sealed to families in which they do not belong.
