It does not appear into whose hands the Tattershall estate fell after the death of the Lord Treasurer Cromwell, until the year 1487, when Henry the seventh granted the manor to his mother, Margaret, Countess of Richmond, and in the following year entailed it on the Duke of Richmond. The Duke dying without issue, Henry the eighth in 1520, granted it to Charles Duke of Suffolk, by letters patent, which were confirmed by Edward the sixth, in the year 1547. On the death of the two infant sons of the Duke of Suffolk, who survived their father only a short time, this manor again came into the possession of the king as one of the heirs general of the family. By letters patent, dated the fifth of September, 1551, Edward the sixth granted the castle with the manor, in fee, to Edward Lord Clinton and Saye, afterwards Earl of Lincoln. The Earl dying in 1584, was succeeded by his son Henry, who died in 1616, leaving issue a son and heir Thomas, who survived his father only two years, and was followed by his son Theophilus, who died in 1667. The next possessor was Edward, who was the grandson of Theophilus, and who died at Tattershall in 1692; in him terminated the male line of the Clinton family. Upon his death, without issue, the Tattershall estate became the property of his cousin Bridget, who married Hugh Fortescue, Esquire, by whom she had a son and heir Hugh, created in 1746, Baron Fortescue, and Earl Clinton. Upon his death in 1751, his half brother Matthew succeeded him, but dying in 1785, the Tattershall estate descended to his eldest son Earl Fortescue, the present possessor. Besides the liberties of the parks, chases and free warrens, belonging to the castle and manor of Tattershall, it also appears in the several grants of Henry the third, Henry the fourth, Henry the seventh, Henry the eighth, and in the grant of the liberties of Richmond fee, whereof the castle and manor of Tattershall is a part, that to the said castle and manor also belong the liberties of stallage, tolls of markets and fairs, together with the privilege for all tenants and inhabitants of Tattershall to be discharged of any tolls in fairs and markets abroad; also the sole liberties of fishing, fowling, hawking, and hunting, in all the said manors, chases and the precincts of them; also suits of courts baron, waifs, estrays, treasure trove, goods and chattels of felons, fugitives, men outlawed, and felones de se, deodands, bondmen, villains, with their sequels; and also that neither the sheriff of the county, nor his bailiff shall arrest within the said manor, and that no distress taken therein shall be delivered, nor replevins granted by the sheriff, but only by the steward of the lord of the said manor. THE CASTLE. About two hundred and fifty yards south-west of the town stands the remains of the castle, a stately edifice, erected by the Lord Treasurer Cromwell, about the year 1440.
