There are quite a few options regarding Emilys birth c1879 but where? - (who died aged 104 in 1983) - I can't see a death for her on Ancestry at all.

There is an Emily BULLOCK born 1879 - who died JFM 1968 age 89 Gloucester Rural - which is way out. Where did she live?

Do you have any more information that would help?
