While it’s always fun to make a genealogical research trip to a courthouse and search through old records, remember that the most fragile genealogical source available is someone’s mind.
If, as the saying goes “Lord willing and the creek don’t rise,” the courthouse will still be around in a week. Great aunt Myrtle might not. The human mind can be extremely fragile and is a repository that often can’t be replicated elsewhere.
Don’t neglect it.
