The National Society Daughters of the American Revolution (NSDAR or DAR), was founded on October 11, 1890, by Mary Smith Lockwood, Ellen Hardin Walworth, Mary Desha, and Eugenia Washington, a great-grandniece of George Washington, not long after the centennial celebration of Washington's inauguration sparked a renewed interest in United States history. From this pioneering group of women to today's vibrant members, the Daughters of the American Revolution have carried the torch of patriotism.  

The Daughters of the American Revolution (DAR) continues to uphold the founding objectives established at its inception:  

Historical Preservation - To honor and remember the individuals who fought for American independence.

Educational Advancement - To champion education as a cornerstone of a thriving democracy, as advocated by George Washington. 

Patriotic Service - To safeguard and promote American liberties, foster a deep love for the nation, and strive for a more just and equitable society for all.

The DAR is a non-profit, non-partisan organization dedicated to volunteer service. It stands as one of the most inclusive genealogical societies in the United States. Membership is open to any woman 18 years or older, irrespective of race, religion, or ethnicity, who can demonstrate lineage from a Patriot of the American Revolution. 

The Harmony Hall Chapter, NSDAR, was organized April 14, 1984, in Fort Washington, Maryland. Our founding members chose the name, Harmony Hall, because of the historic importance of the eighteenth century Harmony Hall Manor located on a 62.5-acre open pasture land estate along the Maryland side of the Potomac River in Fort Washington.

We are very proud of our small chapter and its accomplishments. Comprised of about 25 members, the Harmony Hall Chapter, NSDAR, is a sterling example of women of different ages, from different backgrounds, celebrating patriotism, promoting the education of America's children, and preserving our history. We are dedicated, enthusiastic, joyful, and a whole lot of fun!

While it is true that genealogy and lineage are central to the existence of the DAR, it is the chapter's mission and our strong friendships that make the Harmony Hall Chapter, NSDAR, a group in which we all love to belong.

The chapter generally meets the third Sunday of the month from September through May. If you are interested in attending a meeting to see us in action or catch us out at a community event, please click the email icon at the bottom of the page.

What is called Harmony Hall Manor today was originally called Battersea. Built in 1769 by the wealthy landowner and tobacco merchant Enoch Magruder, the grounds for the house were most likely chosen because it was close to the Potomac River which was the principal means of transportation and shipping during the eighteenth century.

In 1786, Enoch Magruder left the mansion to his daughter Sarah who was married to Colonel William Lyles. In 1792, two brothers John and Walter Dulaney Addison and their new brides rented the house for a year. Elizabeth Hessilus newly married to Walter Dulaney gave Battersea its now well-known name Harmony Hall. Life was pleasant for the young and well to do couples and the name Harmony Hall remained.

Over the ensuing years and a succession of owners the historian, lawyer, and preservationist Charles Collins bought Harmony Hall in 1929 and completed many renovations that are still prevalent today. Originally from Alabama, Collins was an expert in banking law. Part of Collins renovations included the English cow herd ditch, known as a ha-ha.

The remains of an older structure called Want Water or Lyle’s House still stand at Harmony Hall alongside a canal which was built to facilitate the transfer of tobacco. Near the canal once stood an eighteenth-century tobacco warehouse as well as several weighing stations and taxation points for all tobacco shipped to England. The canal may be the earliest man-made canal built in the colonies.

In 1966, Collin's wife sold the property to the National Park Service in hopes of preserving the decades of southern Maryland cultural heritage represented here.
