Holland Society of New York

Upper West Side side streets hold more than brownstones. Some doors open into archives that trace New York’s earliest European threads. The Holland Society of New York keeps one of those doors at 161 W 86th St Apt 1aw, a quiet address that houses manuscripts, family crests, and land patents stretching back to the seventeenth century. Genealogical research and Dutch-American heritage documentation are the core offerings, though the society also publishes scholarly monographs and hosts occasional lectures on colonial trade routes. Visitors can schedule access by calling (212) 758-1675 before making the trip. A map pinpoints the exact apartment entrance: directions here. If you’ve ever wondered why a block in Brooklyn still bears a Dutch name, this is where the answer might be filed.
