The origins of the Manor House and its early history have not been fully studied. In 1872, Edward Trollope mentioned it in his history of Sleaford, writing that "all its details are not honestly known".[3] English Heritage and the architectural historians Sir Nikolaus Pevsner and John Harris date parts of No. 31 to the 17th century and categorise most of No. 33 as mid-18th century and "mid-Georgian" respectively;[1][4] however, local historian Dr Simon Pawley, states that No. 33 is 19th century.[5] An estate map of 1766 shows that the plot was not part of the open field system around Sleaford.[6] A more detailed map, dated to c. 1770, has a building on a plot owned by Robert Banks, corresponding to the location of Rhodes House.[7] An enclosure map completed in 1794 shows a small building at the site, set back slightly from the road and adjoined by a larger one to the north, which faced onto the street; the location and layout also correspond closely to the arrangement of the older parts of Nos. 31 and 33.[8]
By the 19th century, the house was occupied by the banker, businessman and solicitor Benjamin Handley (1754–1828).[9][10] He was Treasurer of the Sleaford Navigation and solicitor to the enclosure commission for Sleaford and several fenland villages, through which service he "amassed a great fortune".[11] It is not clear when ownership of the house changed, but Maurice Peter Moore (1809–1866), clerk of the peace for Kesteven, lived there from at least 1851 until his death.[12][13][14] The son of Rev. Dr William Moore, vicar of Spalding, he was admitted as a solicitor in 1831.[15] Moore was living in Sleaford by 1834, when he is recorded as owning as property on North Street, and was in partnership with William Forbes by 1841.[15][16] Moore married Ann Gardiner Peacock in 1834.[17][18] Their first daughter, Florence, died an infant in 1838[19] and Ann Moore died giving birth to their only surviving child, Anne Louisa Russell (known as Russell), in 1839.[17][20]
Moore considered disinheriting his daughter, writing that "Russell's conduct towards me continues to be cold and heartless ... and I must look on her as not deserving to inherit from me".[17] Sophia Peacock, a sister of his wife, was closely involved in Russell's up-bringing and Moore developed romantic feelings for her; in 1858, he changed his will to give her his property instead of Russell, but Sophia rejected his marriage proposal and he disinherited her the following year.[17] Despite Moore's "vehement objections",[17] his daughter married George Edward Corrance in 1860. After a year she eloped with Colonel Edward William de Lancy Lowe; they married in 1866, after Corrance divorced her on grounds of adultery.[17][21] Her father "had always reason to be dissatisfied with her conduct" and, three months before his death, he made a new will and bequeathed all of his property to Peacock.[20] After Moore's death, Russell Lowe and her paternal uncle, Rev. Edward Moore opened a court case to contest the will.[17] In March 1868, the courts found that the will was legal. Sophia Peacock inherited nearly all of Moore's estate.[20]
Sophia and Ann Gardiner Peacock's father, Anthony Taylor Peacock of South Kyme,[18] was a wealthy banker and his father, Anthony Peacock, was a land-owner, who had worked closely with Benjamin Handley as a sponsor of the Sleaford Navigation and commissioner of enclosures in the 1790s.[22] Among the younger Peacock's other daughters was Louisa, who married Rev. Francis William Rhodes in 1844.[23][24] Louisa and Francis Rhodes's nine children included Cecil Rhodes and Frank Rhodes;[23] they spent their childhood summers with their aunt Sophia at the Manor House in Sleaford and in the Channel Islands.[25] Frank and Cecil learnt to ride at the Manor and it was during these visits to Sleaford that Cecil began his long friendship with Robert Yerburgh, a son of the town's vicar.[25] On Sophia Peacock's death in 1892,[26] Frank Rhodes inherited the Manor House.[27] He was still living there in 1897.[28]
In 1897, Elizabeth Cross rented the Manor House from Rhodes, remaining there until her death in 1923. She moved to Sleaford after the death of her husband, Rev. John Edward Cross (1821−1897), a prebendary of Lincoln.[29][30][31] She purchased "ancient buildings" around Lincolnshire so that their old stonework could be incorporated into the house.[9] It was put up for sale in 1924 and James Gordon Jeudwine and his wife were resident at the house the following year.[9][32] Jeudwine was a son of Canon George Wynne Jeudwine;[33] a solicitor, he became a partner in the firm Peake, Snow and Peake in 1937, the same year that he was appointed Clerk to the Justices of the Sleaford petty sessional division.[34][35] He lived at the house until his death from injuries received in a car accident in 1941.[36][37] The buildings were divided so that the old Manor House became No. 31 and the 18th century part became No. 33 (known as Rhodes House).[1] By the 1960s, ownership had changed hands again: the Manor House was sold by C. B. Cliff to H. A. Mills of Newark in 1967.[38] Mills became headmaster of the William Alvey School in Sleaford. In the 1970s, the owner of No. 31, R. W. Edgely, submitted an application for planning permission to demolish the stables at No. 31 and build a house to its rear; Mills, along with Sleaford and District Civic Trust opposed the plans.[39] From the 1960s to 1992, Sleaford Medical Group practised at Rhodes House and in a building behind it.[40] As of 2015, the building is divided into residential apartments.[41]
