Oh my goodness! That was a fruitless effort. I even signed up and paid for a month's subscription to Forces War Records!! What a scam.
I honestly don't know where to go now 
I’m just not seeing a Samuel Turner occ. Hawker/Fruiterer born Birmingham c1873
that would match with the 1911 Samuel you have in Aston under Lyne

Assuming that it is the same Samuel Turner that marries in Aston 0n 30 Jun 1902 to
Elizabeth Hickling spinster, he gives his occupation as a
FITTER his father
William occ Fruitererhis father William’s occupation is consistent with his 1889 & 1892 marriages to
Mary Dance & Sarah Fulwell
and on all the marriage certs it looks as if Samuel Turner has signed his name
there is no (x) ‘the mark of’ next to his name on all the m/c yet on the latest census
after the signature of ST circled we have the initials of the Enumerator

maybe worth checking Elizabeth Hickling and the address given on their m/c
they were both were living at
24 Bevington Road from
Midlands, England, Electoral Registers, 1832-1955 they were not living at
24 Bevington Road in 1912 that's the earliest date I could find

We know that Selina Turner nee Fulwell died in 1902 but what about his first wife
Mary Turner nee Dance from the 1891 census born Sheffield
Mary Jane Dance age 2 born Sheffield with parents Francis & Catherine on 1871c
https://familysearch.org/pal:/MM9.1.1/V518-3XY and
Mary Dance age 12 born Sheffield with her parents Francis & Catherine in 1881c
https://familysearch.org/pal:/MM9.1.1/X3VQ-7N5Looking back at the 1902 m/c I can trace Elizabeth Hickling with her parents BUT
cannot find her on the 1901 census and has she died before 1911

Here's the censuses I have found for her
from marriage cert. her father is Edward engine driver wit. is a Frederick Hickling
1881c RG11; Piece: 3033; Folio: 29; Page: 49 show us that
Elizabeth Hickling was born c1874 Aston Warwickshire dau of
Edward occ engine driver& Anne living in Liston Pl Lingard St Aston siblings Robert J, William, Alfred, Ann, Elizabeth,
George & Thomas H
1891 RG12; Piece: 2424; Folio: 86; Page: 38
she’s
Eliza age 17 pob Birmingham still at home with parents & siblings
she has a brother
Frederick J age 11
Her brother
Fred Hickling age 19 is with his widowed mother Ann & brother Thomas living in Aston
1901cAs I can't find Elizabeth/Eliza Hickling born c1874 on the 1901 census either

Perhaps she and Samuel are together somewhere

I have just a message back from the ancestry tree for Fulwell and it seems that they have a living Fulwell who was married to their sister and are not in contact with him but they are trying to get a email address for him so that smackie and the living descendant can make contact.
So maybe he is the key to the information on Florence and Elsie. 
Keep my fingers crossed
