I can trace phone numbers from Essex until my parents moved to Cookridge in 1960. As they split and divorced very quickly after that I doubt that number got into the directory.I wondered if it was possible to supply any further information or the names of any of the occupants, which may make it possible to trace via Ancestry or Telephone Directories, in order to identify the locations.
A telephone number appears for my father in Garforth in 1961 and mother in a flat at Roundhay Road in 1962.
My mother bought a house in Leeds 9, but there was no phone and my father appears in the directory for Vesper Road from 1970 onwards
I know my mother bought a house on Roxholme Terrace, probably around 1973, and then appears in a phone directory in a flat at LS17 in 1975 - she died shortly after that.
I can trace my father back to the crusades with ease, but it would appear my mother was a ghost until she married my father in 1953 - and then only appears in phone directories post divorce and a death certificate.
Interestingly my grandfather and descendants all came from London, but my father was born in Ilkley - he (my father) had a sister that died in Ilkley in a school accident just before he was born in 1927 - I'm waiting for Ilkley library to open to see if there is anything in archived copies of the Ilkley Gazette, as Ancestry and local history groups cannot find anything.
Shortly after my father was born they moved to Sussex.
