Great Nine Partners Patent

The first ten, granted between 1685–1697, covered almost all of Hudson River shoreline in the original county, with three - Rombouts, the Great Nine Partners, and Philipse Patents, extending significantly inland.

The twelfth, and next smallest, Fauconnier, in 1703, completed the Hudson River shoreline.

The grant followed the Nine Partners' purchase of approximately 145,000 acres (590 km2) of land from the Wappinger "native Indian proprietors" of central Dutchess County: Perpuwas, Sasaragua, Makerin, Memram, Shawanachko, Shawasquo, Tounis (son of Shawasquo), Acgans, Nimham,[a] Ouracgacguis, Tagahams, Seeck, Cocewyn, Mamany, Arye (Seeck's Son), Wappenas, Tintgeme, Ayawatask, Nonnaparee, and Kindtquaw.

[2] Two years later, land bordering the Hudson River comprising approximately 12,500 acres (51 km2) was divided into nine "Water Lotts".

The Nine Partners company began a written record of their activities in 1730, when the land began to be surveyed, and a book containing minutes for approximately 150 meetings from 1730 through 1749 is held by the Dutchess County Historical Society.

The Great Nine Partners Patent spanned from the Hudson River in the west to The Oblong along the Connecticut border in the east, and was largely bounded by the Little Nine Partners Patent to the north and the Beekman Patent to the south
