The History of the Several Towns, Manors, and Patents of the County of Westchester (1881 revised edition, Vol. I)
In the palmy days of the manor, the tenants brought hither their grain to be ground, and from hence the lords of the manor shipped their flour for the metropolis.
The keel of the famous Roebuck that so often navigated the neighboring waters with her cargo to and from the city, quietly reposes in the muddy bed of the Pocanteco creek. The old miller (who lived to the advanced age of 94,) was in the habit of calling it his iron mine, as the keel actually furnished him with bolts and nails for his lifetime.
The manor house was for many years the residence of the late Mrs. Cornelia Beeckman, widow of Gerard G. Beeckman, Esq.
The old house is full of associations. In 1756 Colonel George Washington, then Commander-in-chief of the Virginia forces, had occasion to communicate with General Shirley, and for this purpose left his head-quarters at Winchester and travelled to Boston on horseback, attended by his aides-de-camp. On his way he stopped in New York for a few days ; and, while there, was entertained by Mr. Beverly Robinson, between whom and himself a strong friendship existed. It happened while he was the guest of his host that he met Miss Mary Vlypse, or, as we spell it now, Philipse -- the daughter of Vrederyck Vlypse, who was born and reared here -- and was deeply impressed by her rare accomplishments and beauty. " My father," said the narrator, "used to tell it as a fact, well established in his day, that the Colonel once rode up here to pay his respects to the object of his regard. However that may be, it is certain that he did stop at the castle very frequently in after years, when the country was in the throes of the Revolution."
