Would you please type up the info as per the 1958 death registration .... You see, the online index clearly has RYDE as the registration place for Florence SANDRY, and that same index entry does NOT include a middle name.
The headings for that registration
Full name of the deceased,
sex and age at death,
date and place of death,
place of residence,
usual occupation
marital status at death
Place of marriage/s, (Each marriage should be listed separately, and the children of each marriage listed under their respective parent)
age/s when married,
full name of spouse/s
Children's name and ages
Parent's names and mother's maiden name
Cause of death and duration of last illness
Burial or cremation date and place
Funeral Director
Name of Informant, and relationship to deceased.
It is quite possible that there is information on the dc that is not as reliable as you would want. However, even if you suspect it is not correct info, often these 'flawed' pieces of info can help resolve some apparent brickwalls.
Cheers, JM
