The Post Office was
originally established as Shamrock Mills, under
Postmaster Charles Clark on June 26, 1839.
It name was changed to Shannock Mills on
January 22, 1861 and it became Shamock for
11 days on October 6, 1884. It's name was
officially changed to Shannock on October
17, 1861. This appears to be due to clerical error on
the part of Postal authorities in Washington, D.C.
