1654; and Markyate Cell, which had been leased to tenants in the years after her father's death, and the farms around it, were disposed of the following year. After Cromwell's death in 1658, The Protectorate did not endure and the monarchy was eventually restored to power. Thomas Fanshawe had become involved in Booth's uprising, a Presbyterian rebellion in the north of England, and was imprisoned in the Tower of London in September 1659, although he was released in February 1660. Charles II entered London in May; Katherine is known to have lodged in the Strand during the celebration. She then died sometime in the first two weeks of June, at the age of 26. Described in the parish register as “Mistress Catherine Fanshawe", she was buried at St Mary's church in Ware, on 13 June 1660. She died childless; this could have been due to infertility, or to her husband's continued absence due to war and imprisonment. A family history written by Herbert Fanshawe in 1927, which draws heavily on the memoirs of Ann, Lady Fanshawe, suggested that: "Possibly her death occurred at the birth of a child for the Register of Ayott St. Lawrence (no great distance from Ware), gives the burial, on 22 November in the same year, of "Marie Fanshawe daughter of Sir Thomas Fanshaw"." If this was indeed Katherine's five-month-old child, its birth was not recorded, and its burial entry would have to have been inserted some time after its death, since Thomas was not knighted until well after 1660. A later entry of this type would not have been unusual for the time, as many parish registries were irregularly kept. However, since Katherine's husband was imprisoned in 1659 following the Booth uprising in the north, and not released until February 1660, the issue then becomes one of paternity, since a pregnancy of four months duration, during those times, could not have produced a child that would have survived. While it is "no great distance from Ware" (some 13 miles), the child in question was not still buried in the same location as Katherine. With Katherine's death the Ferrers line died out; in the following year Thomas Fanshawe, who had been created a Knight of the Bath by Charles II, disposed of the bulk of the Ferrers' family property that had originally been granted to Katherine's ancestors by Edward VI.
