Ooh, I'm sorry, I forgot to say it was the 1911 census. Thank you Mabel for pointing that out

I found the record at FindMyPast but it's also on Ancestry. I can't see any other info. about it and agree that Surrey Archives are the best bet.
I think that the Maria A HARDY that dies in 1957 is a Maria Antonietta HARDY.
Regarding the Maria HARDY that dies in 1940 I think it would be worth looking her up in the 1939 Register. I think she is a patient in the "Public Assistance Institution" in Uckfield. I think this comes under the Uckfield Poor Law Union.
I found this website difficult to navigate but maybe it's me. Eventually I found that if you search for "Uckfield Poor Law Union and Uckfield Public Assistance Institution" then view the record and click on "Uckfield Poor Law Union" a lot of record items show up buut I think you will have to contact them to view individual ones.
