It seems rather clear that the John DANCY shown in the 1624/5 Census as Sir George SANDYS servant was still living in the period 1636-8, as he is named in four Virginia land Patents from this period. These Patents are:
John DANSEY's Patent of 31 Mar 1636 for 100 acres in James City County

The former tract Claybank seems to be near the area where the John Tyler Memorial Highway crosses the Chickahominy River:http://msrmaps.com/image.aspx?T=2&S=12&Z=18&X=41...
A place called Claybank Landing is still actually shown on today's map!
The first three patents generally describe locations "Northwest" of the Chickahominy, which is a little confusing. The river is flowing in a generally Southerly direction at this point, though it generally flows from West to East separating Charles City and New Kent Counties. The "North Bank" would generally be what we now think know as James City County and New Kent County. The South and West Bank of the Chickahominy is that area now known as Charles City County. So these patents may have actually been on the west bank of the River in what is now Charles City County.
The 1638 Patent for 700 acres seems to be about four miles to the North. This land seems to abut land of William HAYE, as well as Theodore MOYSE (2,000 acres Patented on 23 May 1637).
