Maps of Somerset County and Old Somerset

Historic maps are among the most useful tools for Somerset County research. County boundaries, hundreds, election districts, waterways, roads, landowners, and place names changed over time, so a map can often explain why a record appears in a neighboring county or under an unfamiliar name.
