Carew's estate at Coulsdon was joined to the honour (set of manors) of Hampton Court. In her first year of reign, Queen Mary I granted the estate to Carew's son, to be held in chief by the service of one-fortieth part of a knight's fee. In 1589, owing to the imminent default of male heirs, Queen Elizabeth I of England granted the Coulsdon estate to Carew's grandson, Edward Darcy (the son of his daughter, Mary Carew), who was knighted in 1603.
