Hi Margaret, The date is showing as born in the 1960's because of the privacy setting you have chosen for his profile. Only you as the profile manager can view his complete profile and dates etc. All other WikiTree members can only see his public profile view. At top of Frederik Beers profile click the tab that says public view and then click private view to compare what is seen by other members. Click the privacy tab to see the privacy settings and what each does. Norbert is correct February 1958 has only 28 days in the month.
