Something fishy about a 2 year Pregnancy?
One of our ancestors was born 2 years after the death of their father. Now at first one would assume a clerical error on either the birth certificate or the father’s death certificate. Except that oral history confirmed that in this case the person had a different biological father than their 10 sibling. We also had heard that the biological father was well off and left his illegitimate offspring some money and family stories had it that the money was subsequently spent by the partner of this person. So we have to assume that the mother registered the birth claiming her deceased husband as father. This individual was then brought up as part of the mother’s family and we have not seen recorded the name of the biological father.

In familysearch this now comes up with a permanent error. All we can do is record the known information as shown on the certificates and live with the error. I checked with the experts and they confirmed. Record the information available and live with the error. Won’t affect ordinances. If in future additional information becomes available it can then be fixed. So ... just have to get used to living with the error message that a child cannot possibly be born 2 years after the fathers death.

For other error situations and if they can or can’t be overwritten refer to
