Online databases stop short of the county, years or original documents you need.
Put the protocol to work.
Find the county that existed then.
Identify which county had jurisdiction on the event date. A later county may not hold earlier records. Note parent counties and nearby jurisdictions worth checking.
Identify the right office.
Look for the official county website. Deeds, probate, marriages and court files may belong to different offices. Ask which office holds the series and whether older material has moved to an archive.
Ask about coverage before traveling.
Confirm surviving years, indexes, access restrictions, appointment requirements and copying fees directly with staff. Ask whether a remote search or digital copy is possible.
Follow the index to the whole record.
Record book and page references or case numbers. Request the complete deed or case file, not just the indexed entry. For probate, ask whether loose papers survive separately from bound volumes.
Capture the surrounding clues.
Transcribe witnesses, bondsmen, neighbors and place descriptions. Log the office, series, volume, page and date of access so you can return to the evidence.
Don’t mistake a clue for a conclusion.
A courthouse fire does not necessarily mean every record was lost. Ask about surviving series, copies, later transcriptions and transfers to other repositories.
