In 1680 the area around Mount Hope was awarded to the Plymouth Colony, which promptly sold it to a consortium of Plymouth men, including Saffin, the Indian fighter Benjamin Church. This tract became what is now Swansea, Massachusetts, Bristol, Rhode Island, and all or part of other nearby communities. Saffin was also a significant investor in the Atherton Trading Company (named after Humphrey Atherton), whose partners included many of the leading merchants and politicians of both Massachusetts and Plymouth.
