The destruction to Montana courthouses significantly has a affect on genealogists in every way. Not only are most of these historic buildings ripped from our lifetimes, so are the records they housed: marriage, wills, probate, land records, and others. Once destroyed they’re gone forever. Even though they have already been put on mircofilm, computers and film burn up as well. The most heartbreaking side of this is the reason that almost all of our courthouses are destroyed at the hands of arsonist. Though, you cannot assume all records were lost. Many Montana counties have experienced a loss of records due to courthouse fires, floods, and theft.
