 At the beginning of the 14th century, John de Acton split the estate into three parts, conveying two of the parts to John Neyrnoit or Nervett, and keeping one for himself.John Nervett soon re-granted one of the parts back to John de Acton, but henceforth, the estate was generally divided into thirds.That which John Nervett owned became known, from the 16th century onwards, as the manor of Pennington Narvett.
