Compare conflicting ages and birth dates across historical records, then receive suggested records and trustworthy places to search. Suggestions are not verified matches.
How to use: Enter a name (optional), then add one entry for each record. Use the year the person was observed or recorded—not necessarily the year the document was filed. Choose whether the source reports an age or an explicit birth year.
Birth location helps identify birth and baptism sources; residence helps locate censuses, marriage records, and local archives. The original research location above is used as a fallback.

Agreement between records does not prove a date or that the records describe the same person. Sources may copy one another or contain mistakes. Investigate original records and independent evidence before reaching a conclusion.
