This still remains a major problem, she seems to have simply disappeared. I have tried - or at least I think I have - the most obvious things, but to no avail.
As far as I can see, between 1939 and 1971 (when she would have been 100) there are only five Eliza BISHOP deaths of approximately the right age: Q1 1941 Swindon, Q1 1942 Hereford, Q1 1948 Wandsworth, Q1 1957 Stourbridge and Q2 1963 Nuneaton.
If you extend the acceptable error on age at death, then there are three others: Q1 1956 Bethnal Green, Q4 1961 Surrey ME and Q2 1967 Manchester.
I know of no reason why she would be connected to any of those areas.
Not sure what to do next. I could obviously order all the above certificates, but that would cost a fortune and not necessarily provide the answer. Any suggestions?
