Dear Brian,
Research on the internet has revealed two pieces of information which may or may not be relevant. I found a birth for Florence Blunt in Cranbrook registration district, third quarter of 1868, folio 2A, page 617.
In the 1871 census the family were at Old Cranbrook Road, Hawkhurst but Florence was not listed. However in the same census I found a record for a property in Styles Yard, Horsmonden in the names of James and Henrietta Bradford. However, interestingly a Florence Blunt was listed aged five and shown as a Niece.
According to my road atlas Goudhurst, Hawkhurst and Horsmonden are all in the same general area. However, the birth record indicates 1868 and the 1871 census aged five in 1871, leaving a gap of two years, although the census records were not always precise and of course she was not with her parents on census day.
Regards,
fifthwheel.
