Mrs Gurney, referred to in JW's correspondence in 1872, may have been Isabel Blake Gurney, later The Lady Talbot of Malahide. Her son Samuel wrote a book about her in 1935.
The architect Thomas Jeckyll made additions to Cliff House, Cromer for Gurney in 1854, designed or restored farm buildings for Hudson Gurney and John Henry Gurney at Old Catton, Northrepps, Earlham, Northrepps, and Keswick between 1854 and 1862, and rebuilt Sprowston Hall, a small Elizabethan house just outside Norwich for John Henry and Isabel between 1869 and 1876. He designed carriage gates incororating Japanese wave patterns with regularly spaced mon for Sprowston Hall.
The stamped leather used by Jeckyll for the Peacock Room came from Catton Hall, which was owned by John Henry Gurney 1854-1865.
