Worcester County was established on April 2, 1731, Worcester was chosen as its shire town (later known as a
county seat). From that date until the dissolution of the county government, it was the only county seat. Because of
the size of the county, there were fifteen attempts over 140 years to split the county into two counties, but
without success. Initially, Lancaster was proposed as the seat of the northern county; later, Petersham was proposed
once and Fitchburg was proposed repeatedly, most recently in 1903. Perhaps as a concession, in August 1884, the
Worcester County Registry of Deeds was split into two, with the Worcester Northern registry placed in Fitchburg.
