I visited the local library in Folkestone and checked the electoral role.
This confirmed that the residents in 1935 were:
"HENRY JOHN PHILIP SIDNEY ROPER-CURZON
MABEL ROPER-CURZON"
further investigations online I discovered the Times entry:
"22nd December 1936 - "DEATH: TEYNHAM - On Dec. 19, 1936, very suddenly, at Well House, Sandgate, HENRY JOHN PHILIP SIDNEY ROPER-CURZON, 18th baron, beloved husband of Mabel, daughter of the late Colonel Henry Green-Wilkinson, aged 69. Funeral to-morrow (Wednesday) at 2.45 p.m., Lynsted Church (station, Sittingbourne). Flowers to Well House, Sandgate." (Category: Death)
24th December 1936 - "FUNERAL: LORD TEYNHAM: The funeral of Lord Teynham took place at Lynsted, near Sittingbourne, yesterday, the service being conducted by the Rev. L.E.A.Ehrmann, assisted by the Rev. H.G.Blackbourne, who read the Lesson and took the committal at the graveside. The mourners included:-
Commander the Hon. Christopher and Mrs. Roper-Curzon (son and daughter-in-law), the Hon. Ralph Roper-Curzon (son), the Hon. Harriet Roper-Curzon (sister), Captain Green-Wilkinson (brother-in-law), Lady Edward Spencer-Churchill, Mr. and Mrs. Randall Kenyon (brother-in-law and sister-in-law), Commander and Mrs H.G.Joyce (brother-in-law and sister-in-law), Captain R.M. Watson (nephew), Mr. Temple Harris, R.N. (nephew), Mr. and Mrs. W. Roper-Lumley-Holland (cousins).
Mr. C.W. Nevill, Mr. Roderick Nevill, the Hon. Mrs. Mark Hovell, Mr. A.F. Sims, Captain Faunce-De Laune and Mr. Hubert Faunce-De Laune, Lady Harris (also representing Lord Harris), Captain T. Croft, Mrs. D. Graham, Major A.J. Peareth (also representing Major-General Sir Arthur Lynden-Bell and the Past and Present Association of The Buffs), and Miss Mildred Smith." (Category: Funeral)"
Now following up the subsequent occupiers and trying to look back at any previous owners/occupiers, but it could be this (1934/35) was when the house was built. There are no previous records in the electoral register, plus ties in with the OS map.
Interestingly the current number is 41 Radnor Cliff.
But the electoral register shows the address between no.s 19 and 22.
Anyone know how to research road numbering, specifically re-numbering??
