New Castle County, Delaware
In 1682, Delaware came under the proprietorship of William Penn, but it was administered separately from Pennsylvania as a distinct entity called the "three counties of Delaware".Delaware became, in 1787, the first state to ratify the U.S. Constitution. William Clouds land was laid out and surveyed, to the southward of Namaans Creek, but part of it was later found to be in New Castle County, in the northern part of Pennsylvania Province. The land was located in Rockland Manor, Brandywine Hundred, New Castle County, Pennsylvania, about six miles north of what is now Wilmington, Delaware. William does not appear to have settled upon his land as he lived and died in Concord Township, Pennsylvania Province.
