Possible Causes

- Poor guess of unknown birth date and/or death date.
- The birth and death date are put in the reverse fields.
Action Steps
Correct this error by:
- Correcting any typos based on information found in the profile. If no information is found then...
- Research to find a source which will determine the correct birth and death dates. If no sources are found then...
- Replace date(s) with a reasonable guess based on a date of birth, death or marriage or the birth date(s) of family members. Mark the date(s) as "Uncertain." Leave a note in the profile stating that the date is an estimate and what you used as a comparison for estimation.
- If the profile has no sources and no relatives and no reasonable guess can be made, delete the single date which is clearly incorrect (rarely needed). Add a note in the profile regarding what was in the date field and why it was removed.
