List of Washington Extinct Counties
Washington contains counties that no longer are in existence. They were recognized by the state, provincial, or territorial government. Most of these counties were created and disbanded during the Nineteenth century; county borders have modified very little since 1900 in the vast number of states. These counties really should be considered when you are performing genealogy and family history research. Pay attention where the courthouse records went to if the county was abolished or joined with another county.

List of Washington Counties with Burned Courthouses
The destruction to Washington courthouses tremendously has a effect on family historians in almost every way. Not only are these kinds of historic buildings ripped from our lifetimes, so are the records they housed: marriage, wills, probate, land records, and others. Once destroyed they’re destroyed forever. Despite the fact that they have been placed on mircofilm, computers and film burn as well. The most heartbreaking side of this is the reason that almost all of our courthouses are destroyed from arsonist. However, don’t assume all records were lost. Numerous Washington counties have dealt with a loss of records due to courthouse fires, floods, and theft.

Many county records were destroyed, including probate records, Superior and District court records, and records of the Sheriff, Superintendent of Schools and Surveyor’s office.
