[JenB]

Who needs google with you lovely people thank you     thank you so much

I used another free source for the death entries - freebmd.https://www.freebmd.org.uk/search

And I used Family Search ( also free) to find them in 1911

Helen & Theodore both children of Mary Diane
Both died young, Helen in 1908 & Theo in 1901

You should be able to do a free search on FindMyPast to locate them in 1939.  We are not allowed to do lookups from that register.

Hitchcock - On December 20th 1946 Theodore Hitchcock passed peacefully away aged 84 years: also on December 21st at 5 Granville Street Mary Diana his beloved wife age 80. Funeral Tuesday. Service and interment Nottingham Road Cemetery 2.45 pm


British newspaper archive also allows free searches.  I believe that you can get 3 free copies on their trial.
