Or the county Prothonotary.
I'm suspecting that you might be an older Pittsburgher.
From Wikipeadia:
U.S. President Harry S Truman was introduced to a prothonotary during a campaign stop in Pittsburgh in 1948.
It is widely rumored that Truman's first reaction upon hearing the term "prothonotary" was to say "What the hell is a prothonotary?"
