Is that possible? You can use the List of People report for either of these. The "military service" part may be a bit harder in that you would probably have to run the report multiple times -- each filtering for one or more different Tag Types depending on what Tags have been used for military service. For example, you might have a filter like: Milit-Beg... # of Tags =Equals 0 END Then you might have essentially the same filter for any other military serice Tags that have been used. Using Custom Flags to "track" the different combinations of persons having Flags set/not set and/or set with various settings, y6ou could realize your goal. For those born before a date without a Death Tag, a similar filter to the above for the Death Tag AND a filter like: Birth... Date < Comes before [?] END would give those candidates for a Death Tag Lee
