Established in 1974 as a “Friends” group, today the Wallace House and Old Dutch Parsonage Association is a 501(c)(3) nonprofit corporation dedicated to the preservation and restoration of these New Jersey and National Register of Historic Places sites.​Supplementing the efforts of New Jersey's Division of Parks and Forestry, the Association raises funds for furnishing, restoring, and improving the sites as well as preserving and interpreting their place in New Jersey’s and the nation’s heritage. The Association also serves as an advocate for the sites and networks with other local historic groups on multi-site events and programs.
