"Suffolk County's observance of the nation's Bicentennial took an unusual turn this week with the informal unveiling of two plaques reflecting the history of an East Patchogue property that has been in the same family throughout the nation's entire history.
Announcement of the plaques was made by Humphrey R. Avery, seventh generation of the Avery family to own the property, which once extended from Blue Point to Bellport.
The bronze plaques are imbedded in an immense boulder that stands close to the South Country Road boundary of the Avery tract, which today consists of about 90 acres. Close by is a small frame dwelling built in 1820 as the Avery homestead.
One plaque lists the following succession of Avery family members who owned the property and their respective life spans:
Humphrey Avery, 1699-1788; Humphrey Avery, 1725-1789; Roger Avery, 1755-1824; John Avery, 1791-1868; Humphrey Avery, 1816-1889; Charles W. Avery, 1854-1915; and the present Humphrey R. Avery, who uses the property as the Swan River Nursery, whose trees are sold nationwide.
The second plaque reads: "Site of a homestead. This is part of land sold by Tobaccus, Sachem of Unkechaug Indians, to Gov. John Winthrop of Connecticut in 1664, extending from Bellport through Blue Point, from Great South Bay to the middle of the island. By 1680 it was known as "Winthrop's Patent'. Humphrey Avery, of Preston, Conn., purchased the Pine Neck from John Still Winthrop in 1752. He sold the land by lottery in 1756, repurchasing the lot on which the Swan River Nursery office now stands, built in 1820 as the Avery homestead."
Mr. Avery said the purpose of the plaques is to acquaint the general public with the history of the tract. His plans, he declared, call for deeding a small parcel of land containing the boulder-memorial to Brookhaven Town "in the hope that the stone will remain there forever."
Mr. Avery, his wife, Mrs. Mildred Avery, and their daughter, Miss Barbara Avery, live close by the old Avery homestead, which now serves as the nursery office.
