The Townsend Society of America is located in historic Oyster Bay, Long Island. The original museum and archive was in a Victorian house purchased in the early 1980s with a bequest to the Society by Miss Helen Hart Townsend.  In accordance with her wishes, the museum was dedicated to the memory of her great-grandparents, Samuel and Rebecca Purdy Townsend. The Society has since closed the museum and dedicated its resources to better serve members with their research.

In July 2017, the Society moved to 123 South Street in downtown Oyster Bay and we are in very limited space. We have maintained our collection of Townsend memorabilia and genealogical material.

We are around the corner from the Raynham Hall Museum which was the family home of Robert Townsend, the Culper Spy. Next door is the 'old' Townsend Inn (now a Masonic Lodge) and a Victorian-era Townsend house.  You can also visit the Oyster Bay Historical Society or tour Sagamore Hill, Teddy Roosevelt's house, which is part of the National Park Service.  Please see their websites for days and hours open.

Our hours are by appointment only, generally evenings or weekends. Please keep in mind that our office is quite small and not able to accomodate more than a couple of persons. We do not have research tables. Members of the Society are welcome to attend the Annual Meeting in October which is no longer held at the office but at a location to be announced.  If you would like to visit us or plan to attend the Annual Meeting, we request that you let us know ahead of time.  You can call (516) 558-7092 or send an email to:  There is parking behind the building.
