New online family tree consistency checker on MyHeritage

My Heritage ( has announced that it is adding a facility to its online family tree hosting facility which has previously been available on its Family Tree Builder programme. From the announcement:

The Consistency Checker employs 36 different checks on the family tree data, ranging from the obvious (e.g., a person was born before their parent, or when the parent was too young to be a parent) to the subtle and hard to find (e.g., a person was tagged in a photo and the photo is dated before the person’s birth; or two full siblings were born 5 months apart, which is impossible). Some of the issues it finds are factual mistakes (e.g. wrong birth date entered), some are bad practices (e.g. birth year entered as 22 instead of 1922, or prefix entered as part of the first name instead of in the prefix field), some are warnings about possible data entry errors (e.g. a woman’s married surname was apparently entered as her maiden surname, or a place was entered that looks suspiciously like a date) and some are inconsistencies you may want to fix, such as references to the same place name with two different spellings. Any issue you feel is fine and should intentionally not be addressed can easily be marked to be ignored and will not be reported again.

The full announcement is available at
