I have been researching the history of the area where I live.
Around 1875 Marshall Nisbet Inman, architect, of 7 Bedford Row, London, drew a master plan for the ‘Belmont Estate’ in Sutton, Surrey. In 1882 he took out a lease of the estate.
A small part was developed at that time, but the rest held fire until 1898 when the lease was converted into a freehold in the names of Marshall Nisbet Inman, Henry Beale Inman of Rickford Lodge, Hampstead, and Annie Letitia Inman, widow, of Carlingford, Worsley Road, Hampstead. In November 1901 Henry Beale Inman changed his middle name to Reid by deed poll.
In 1921 Ronald Kesterton Inman, surveyor, of 6 Dorset Square, London, and Edith Inman, spinster, of 71 London Road, Tunbridge Wells acquired an interest in the estate in consideration of loans made to H R Inman.
Development of the estate was virtually completed by the mid 1920s, with individual householders acquiring their freeholds from H R Inman, at which stage the family connection appears to have ended.
Hope this is of interest.
