Back when I used to do pedigree analysis, the general rule of thumb was 1/10 chance that the father wasn't what was stated in the pedigree.
You would run the analysis and get absolute nonsense results, and then you'd swap a father for an uncle, or a mother for her daughter, and the alleles would all just suddenly line up.
We would never tell the families, and since the pedigrees were anonymized before being published there was no need to. Some secrets are just best kept buried.
