Ann Richbell procured a warrant from the Governor to survey the easternmost bounds of her lands. The surveyor, Augustine Graham, proceeded along the west bank of Mamaroneck River until he came to the " improved land claimed by Humphrey Underbill, where the said Underbill, with three others, with guns, stones and staves did obstruct the execution of his Excellency's warrant." Mr. Underbill was a man of high standing in the estimation of his townsmen, and Dr. Baird supposes he was a son of the famous Captain John Underbill.

On the hill west of Humphrey Underbill, and near the road, stood the house of Samuel Merritt ; about a quarter of a mile north of Merritt's, and near the present residence of Mr. Seymour, was the house of the patentee Samuel Hunt ; he had a tract of three hundred and eighty acres, and a mill on Mamaroneck River, easterly from his house. Northerly, on the same North Street road, were the residences of John and Samuel Hoit, active men in town afi'airs, who in 1726-27 were leaders in building the Presbyterian Church.

On the north side of the road crossing Bronx River, near Mr. Champanois' residence, was the house of Christopher Yeomans ; Anthony Miller lived where the Misses Tompkins' housestands, north of the cemetery, and his fulling-mill was on the brook, south of the house. These were all the houses in White Plains at the date of the patent, and all the occu]iants were men of sufficient education to read and write.
