I have two people who are mentioned in a sibling’s 2005 obituary as having predeceased him, so I know they’re both dead, but not idea when they died, except that it was aftr the 1940 Census and before 2005. Normally I would enter “before 2005” for the date of deathl, but the system is insisting it will only accept a specific date. What is the approved wapy of handling this so that these people are not mistaken for living non-members?
