Our Mission

The Union Township Historical Society's mission, with community support and involvement, is to preserve and promote the rich and diverse history of the Township of Union, Union County, New Jersey.


The collection and preservation of historical artifacts, photographs, manuscripts, published works, and other materials related to the history of the Township and its residents is fundamental to this mission, as is the preservation of the 1782 historic Caldwell Parsonage, which serves as the Society's museum and headquarters.


Also fundamental to the mission is encouraging the preservation and appreciation of historic sites and structures within the Township.  In support of this mission, the society displays its permanent collection, mount exhibits, develops and implements educational  programs, issues publications, and makes its resources and expertise available to the public.


Joanne Rajoppi to speak on November 10

           On Sunday, November 10, the Union Township Historical Society will host Union County Clerk and author, Joanne Hamilton Rajoppi, at Connecticut Farms Presbyterian Church, 888 Stuyvesant Avenue, Union.  At 3 pm, she will present "Revolutionary Elizabethtown and Connecticut Farms,” based on the research for her newest work, a novel about the story of Elizabethtown in the volatile years, 1777-1780, when the American Revolution seemed doomed.  Ms. Rajoppi has written two historical non-fiction works about New Jersey history and now relates this exciting era of the colony of  New Jersey, and focuses on the men and women who played key roles in changing the course of our history and whose presence is still felt today.

          Admission to the event is free.  Refreshments will be served.
