HISTORY OF AVESTCHESTER COUNTY.

Partition of that year of the undivided portions of the Manor of Scarsdaie. Subsequently John Peter de Lancey the son of Mrs. De Lancey who had succeeded to some of his mother's lauds purchased all the rest of the lands on De Lancey's Neck from his brother, and sister, and cousins, and thus became the owner of the whole Neck, nearly a century ago. There was however a small piece of land of about thirty acres on the left of the entrance to the Neck from the old Westchester Path or old Boston Eoad, which never belonged to the Manor of Scarsdaie nor to the Heathcote or de Lancey families. This piece was given on the 8th of August 1684, by Mrs. Richbell just after her husband's death, to her daughter Mary and her husband Capt. James Mott, and was expressly reserved in her deed to Colonel Heathcote of all the rest of her estate in Mamaroneck. This piece from Mott's heirs passed by sale through various parties and about a century ago became the property of a venerable Quaker long well known in Mamaroneck, Giles Seaman. At his death in the settlement of his estate it was bought by the late Isaac Hall, and by him it was sold to the enterprising gentleman who upon it erected the handsome summer hotel, since called by his own name -- the " Rushmore," as well as several handsome private residences, now owned by various parties.
