The Charter required a layout of the land. In accordance, a survey was made of the towns of Chesterfield, Westmorland, and Walpole by Josiah Willard and Benjamin Bellows. This was finished in March 1752.

However, the French & Indian War 1754 – 1763/4 put off settlement of the town. (It is also know as the 6th Indian War or the Seven Years War which ended at the Treaty of Paris.)
The town lot layout may have been done in 1760/1 as that is when the first deeds were recorded. There are 16 “ranges”, each range is divided into lots of 100 acres each (more or less), and having a length of 160 rods, (measured from east to west, and a breath of 100 rods. They are numbered from south to north. (A rod is equal to 16 1/2 feet.)
The Charter proved that “town-lots” of 1-square acre should be laid out as near the center of town as the land would permit. It is not known if these lots were laid out or not. But some of the 100 acre lots are divided into half-lots or “50-acre lots”, which are designated in old deeds as “house-lots”.
Gov. Wentworth’s share was speculative, and it is unknown what happened to it. Part of it was purchased or in some way deeded to Samuel Davis. In 1780, all 300 acres were purchased by William Randall.
