Bereavement studies which have correlated mental illness and other pathology with the recent or past deaths of parents have relied on the subject's memory for ascertaining parent death dates. Data given by subjects can be wrong, because of faulty recollection or deliberate misinformation given to conceal something felt to be shameful, such as illegitimacy.
