This link comes to us from the Genealogy and Heritage Library (GHL) of the North Carolina State Library. GHL staff note the problem of Court fires, which have wiped out a fair amount of of vital records over the years. Here’s their characterization of the problem in North Carolina:
In North Carolina, 36 out of 100 counties have records lost due to courthouse fires. In addition, there are 32 more counties that have missing records for unknown reasons. That is about two-thirds of the counties in North Carolina with missing records. Missing records like this can create brick walls, which are a bane to genealogists, but something we must deal with at times.
North Carolina is not alone and its not just fires in court houses. There are few 1890 Census records for Alaska due to a fire.
