Westborough is a town in Worcester County, Massachusetts, United States. The population was 18,272 at the 2010 Census, in nearly 6,900 households.
The early English explorer John Oldham followed these trails through Westborough in 1633, and settlers in search of fertile farmlands followed not long after. By late 1675, a few families had settled near Lake Chauncy, in the "west borough" of Marlborough.On November 18, 1717, Westborough was incorporated as the hundredth town in Massachusetts, populated by twenty-seven families, including Thomas Rice who had represented Marlborough in the Great and General Court. Soon large farms were carved out, mills built along the Assabet River and Jackstraw Brook, and taverns flourished. Westborough's first minister, Reverend Ebenezer Parkman, shepherded the growing town of colonists through the years toward independence from Great Britain. Forty-six minutemen from Westborough fought under Captain Edmund Brigham in the Revolutionary War.
