Justin: Hello & welcome - haven't you been busy in the last few days ! Good work.
As to your question, my short answer would be: When ? Where ? Who ? if you are seeking confirmation of an actual date that has already been recorded by someone, somewhere at some time.
In the absence of a known starting point you may have to resort to records which might provide approximations, e.g. census records, death records for parent/s or the subject person, gravestones/memorials, local newspaper notices etc., etc.
I'm sure there are any number of ways to find the key to the lock if, in fact, the lock exists and is not too remote - either in time or location.
I believe the experts within WikiTree could assist you more directly if they had info on the above unknowns. Regards Phil (Grace-883)
