Ira: I try to reference each piece of information that I enter into my database to the source from which it came. Many of the sources I use are very old church records and family bible entries, the dates of many of the events (births, marriages, deaths, etc.) from these sources differ. The criteria used to identify the Event date to be displayed on the Family Group Window appears to be the "latest date" in the Individual's Edit Window for the Event. A suggestion would be the "Sur" field entry - for example a SUR=3 would identify the event date as the most probable and therefore the date to be displayed on the Family Group Window and also any other window or report the displays a most probable date. Thanks for all you past help and interest. Bill LaBarge
