So I've had a harder look. Aquitaine, why do you think that the Elizabeth Smith who died in Kensington St in 1915, and who (according to the paper) was the widow of John Smith, had the maiden name Goodman?
Tracing back, this is what I see:
1911- Elizabeth S at Kensington St with son Edward who is 46.
1901 - Same address, sons Edward age 36 and Joseph age 51.
1891 - Orchard St, son Joseph age 41.
1881 - Orchard St - son Edward age 16, husband John (chimney sweep).
1871 - Orchard St - son Enocks Enoch age 16, Edward age 6; daughter Ann age 13; husband John age 46.
11 July 1847; John SMITH m Elizabeth MATTOCKat St Margaret. Both of full age; John a chimney sweep. NO father given for John; Elizabeth's father was Joseph Mattock, a carpenter. Witnesses John and Elizabeth Baines.
Children with surname Smith and mmn Mattock (or v similar):
Joseph (1849) (Maddock)
Enoch (1854) (Maddocks)
Edward (1864) (Mattick)
and possibly Ann (1857) (Mattil)
In 1861, 6 year old Enock Smith is with his grandmother Alice Mattock.
I'd suggest that EITHER your Elizabeth died in Kensington St, had the maiden name Mattock, and is nothing to do with any Goodmans
OR your Elizabeth was a different person altogether (and didn't die in Kensington St!)
I think it depends really on the evidence you're using for which is your Elizabeth. But clearly there are at least 2 different Smith families muddled throughout this thread.
