Abby Aldrich Rockefeller Folk Art Museum (Virginia) The Abby Aldrich Rockefeller Folk Art Museum (AARFAM) is the United States' first and the world's oldest continually operated museum dedicated to the preservation, collection, and exhibition of American folk art. Located just outside the historic boundary of Colonial Williamsburg, Virginia, AARFAM was founded with a collection donated by Abby Aldrich Rockefeller and an endowment from her widower, John D. Rockefeller Jr., heir to the Standard Oil fortune and co-founder of Colonial Williamsburg.
