You need to put dates of birth on these profiles. If you don't know the dates, estimate to the best you are able and select the little radio button under the date of birth field for about/uncertain. Then in the bio field write-in that the age is an estimate. There is a thing for this called a template but since you are just finding your way around you can do that later. Then change the privacy level on profiles of deceased persons if you want others to see the information displayed on the profiles. Otherwise it doesn't allow anyone to see the details of the profiles you manage in order to help you compile information or even answer your question.
