The Geni Consistency Checker will report "Married too young" on any profile where that person's age at the time of marriage was less than 15 years old. This is not impossible, however, so if you're certain it's correct you may click the "Ignore" link at the bottom-right corner of the inconsistency and then choosing "Mark this correct for all users."
Note: marriages prior to 1500 are exempted from this check.
This inconsistency is always considered a Warning
Auto-fix: There is no auto-fix for this inconsistency. The person's birth date may be wrong, the marriage date may be wrong, or they might have never been married.
