The Geni Consistency Checker will report "Person is too old to be alive" on any profile marked living where the birth date or estimated birth date is more than 110 years ago. The severity of this inconsistency depends on how long ago:
Warning - for profiles up to and including the oldest documented person alive
Error - for profiles older than the oldest documented person alive
Auto-fix: Click the button labeled "Mark this profile as deceased" to make the profile deceased.
