Members of the Rotch family dominated Nantucket business and politics across three generations. The rise of this family was linked to the rise of the island as a whaling center. The well-connected family owned two of the three ships involved in the Boston Tea Party on December 16, 1773. According to the Nantucket Historical Association, this warehouse and counting house building was in fact, built in 1775, not 1772, as erroneously stated on the wood plaque mounted on the outside of the building, for William Rotch, one of the pre-eminent figures in Nantucket’s whaling industry. The handsome brick building served as the Rotch Counting House. William Rotch subsequently moved his business to New Bedford. In 1861, the building was purchased by a group of former whaling masters who formed the organization known as the Pacific Club, and the building has been known by its eponymous name and is still owned by the members of the Pacific Club, who are invited into membership on a referral basis and are responsible for its maintenance.
