Henry Packer Dering (1763–1822)

Henry Packer Dering served as the first custom master of Sag Harbor's Custom House beginning in 1790, following his move from his family's home on Shelter Island. Henry Packer Dering was the son of Thomas Dering (1720–1785) and Mary Sylvester. In addition to being a signer of the Continental Association (1774), Thomas Dering served as the inspector of trade and navigation at the Port of New London before the Revolutionary War. Mary Sylvester, daughter of Brinley Sylvester, inherited a large estate on Shelter Island which was then inherited by Thomas Dering when they married, making the Derings a leading family of Shelter Island. Thomas Dering's devotion to the patriot cause played a role in George Washington's appointing of Henry Packer Dering, making him the first customs master to be instated under the new Constitution. In addition to serving as custom master, Dering was also made inspector of the revenue and collector of Sag Harbor in 1791, and postmaster in 1794. He held all three offices until his death on April 30, 1822. With these jobs, Dering was responsible for weighing and gauging cargoes, hearing oaths of registry and citizenship, and overseeing statements regarding truthfulness and reliability of mail delivery. Dering also oversaw the operations of lighthouses Little Gull Island, Cedar Island, and Montauk.^[2]

Henry Packer Dering married Anna Fosdick (1769–1852) in December 1793. He purchased the Custom House, which served both as Dering's office and private residence, sometime before March 24, 1794. Henry and his wife, Anna, lived in the house with their nine children (seven of which lived to adulthood), expanding the structure as their family grew. A number of people the Derings enslaved lived in the house as well. Dering struggled financially, and on May 14, 1842, the family sold the Custom House to cover debts.^[2]

Henry Thomas Dering (1796–1854)

Henry Thomas Dering was the oldest son of Henry Packer Dering and Anna Dering. He succeeded his father and served as custom master from 1822 to 1829, then again between 1842 and 1845, and finally from 1846 to 1849.^[2]

Exterior

The Custom House is a two-story, wooden shingle house located on the corner of Garden Street and Main Street in Sag Harbor. The main façade of the house features five symmetrically spaced bays with two windows flanking the uncovered front door on the first level, and five symmetrically spaced windows mirroring the ones below on the second level. The center portion of the house also has two evenly spaced chimneys, adding to the symmetrical look of the house. The house features two lean-to structures, one on the south side and one in the back. There is also an additional structure attached to the north side of the house.^[2]

Interior

The first floor of the Custom house is organized around a center stair hall located opposite the front door. A custom room and private parlor flank the center hall in the front, while a kitchen with two pantries in a lean-to, a dining room, and a rear staircase are located in the back. Connected to the custom room is another lean-to structure with an exterior entrance that originally functioned as the post office, making the entire south side of the house reserved for Dering's work. The opposite side of the house features a north wing that was once a freestanding structure and was later attached to the main house. It was likely used for additional work-related purposes such as storage for food or goods related to Dering's professional responsibilities. Today, the north wing serves as an apartment. Five bed chambers are located on the second floor.^[2]

Henry Packer Dering

The Custom House has undergone numerous alterations since its original construction circa 1770 as a “half house” featuring three bays with a front door on the right. As initially built, the interior included a side hall, parlor, and kitchen on the first floor, with the three bed chambers, one big and two small, on the second floor. Henry Packer Dering enlarged the house to accommodate his growing family. In 1794, he added a lean-to structure on the south side to serve as the post office. A year later, the building underwent a two-story addition. This extension included a new front parlor, a formal dining space, additional kitchen space in the rear, and bed chambers on the second floor. The ceiling was also raised in the first-floor addition. Lastly, the north wing of the house, which was once a freestanding structure, was attached to the main house, providing additional work and storage space.^[2]

The Old Sagg-Harbour Committee and SPLIA

Interest in the preservation of the Custom House emerged in 1944 when it caught the attention of Henry Triglar Weeks, founder of the Old Sagg-Harbour Committee, an organization devoted to finding, saving, and restoring old buildings in the Sag Harbor area. As the Custom House faced demolition, Weeks worked to save it, recruiting architects like Talbot Hamlin to express their support for its preservation. Finally in 1948, Weeks facilitated the gifting of the Custom House from St. Andrews Church to former Governor Charles Edison's Argonaut Enterprises. Edison provided the land for the Custom House's relocation as well as the funds to dig and build a new foundation. The house was subsequently moved from the corner of Church and Union Street to where it currently stands at the corner of Garden Street and Main Street. In 1955, the Old Sagg Harbour Committee became a non-profit museum and assumed ownership of the Custom House from Argonaut Enterprises, Inc. However, the organization struggled to raise the funds necessary to restore the Custom House in the way they envisioned. On May 2, 1966, the Custom House was given to The Society for the Preservation of Long Island Antiquities (SPLIA), now Preservation Long Island.^[2]

From 1969 to 1972, SPLIA engaged in a major effort to restore, research, and interpret the Custom House. During this time, paint samples were evaluated, wallpaper samples were dated, and various interior restorations were made. Historian Loring McMillen played an important role in this process, recommending the house be interpreted to the period of 1794 to 1810. In 1792, the Custom House reopened for public tours.^[2]
