Hundreds are unincorporated subdivisions of counties, equivalent to townships, and were once used as a basis for representation in the Delaware General Assembly. While their names still appear on all real estate transactions, they presently have no meaningful use or purpose except as a geographical point of reference. The divisions, or “hundreds” as they are called, comes from the times when Delaware and Maryland were colonial holdings of Great Britain. While Delaware alone retains the use of “hundreds”, the origin of most “place names” in both states can be traced back to the times of British rule.
List of Delaware Extinct Counties
Delaware contains counties that no longer exist. They were set up by the state, provincial, or territorial governing administration. Many of these counties were created and disbanded within the Nineteenth century; county borders have modified little since Nineteen hundred in the vast majority of states. These counties really should be investigated when you are conducting family history and genealogy research. Pay attention where the courthouse records went to if the county was eliminated or combined with another county.
