9. Concord Mill Dam Company Stockholders and Property Holdings, April 1838

Extending along both sides of Main Street, the Concord Mill Dam Company's many buildings dominated the Milldam and were valued at more than $10,000. Stockholders included Company owners as well as others, including Cyrus Hubbard, David Loring, Abiel Heywood, John Stacy, Alvan Pratt, and Nathan Brooks. Many of these men were also members of the Social Circle—a self-perpetuating private men's organization—and, consequently, formed part of an elite network that was both socially and politically influential.

This 1838 record of the Concord Mill Dam Company’s stockholders and property holdings provides a wealth of information about the company's status after just over a decade in business

The Stow family was heavily involved in Mill Dam Company ventures. Nathan and Cyrus Stow, along with Abel Moore and Daniel Shattuck, were listed in Private and Special Statutes of the Commonwealth of Massachusetts from May 1822 to March 1830 as incorporators of the Mill Dam Company.
