Hi there,
I've had huge fun with this family. Don't take any of this for gospel, but it all seems to hang in together really well. Here goes:
1891
Quarrington
Turnbull, James S abt 1859 Scotland Head, builder’s merchant
Turnbull, Sarah A abt 1857 Hull, Yorkshire, Wife
Turnbull, Alfred D abt 1890 Sleaford, Lincolnshire, Son
Turnbull, Alice M abt 1890 Sleaford, Lincolnshire, Daughter
Turnbull, John H abt 1888 Sleaford, Lincolnshire, Son
Turnbull, Margaret abt 1885 Sleaford, Lincolnshire, Daughter
1901
6 London Rd, Quarrington
James S Turnbull abt 1860 Scotland Head, builder's merchant
Sarah A Turnbull abt 1861 Hull, Yorkshire, Wife
Alice M Turnbull abt 1891 Sleaford, Lincolnshire, Daughter
Florence Turnbull abt 1893 Sleaford, Lincolnshire, Daughter
Harold Turnbull abt 1888 Sleaford, Lincolnshire, Son
Margaret Turnbull abt 1886 Sleaford, Lincolnshire, Daughter
Emma Greetham abt 1885 Osbournby, Lincolnshire, Servant
POSSIBLE MARRIAGE
June Q. 1884, Bridlington, 9d/518
Spring, Sarah Ann
Turnbull, James Sword
I thought that was pretty much a wild guess until I found the following:
1881
53 South Street, New Sleaford , Lincolnshire
Alfred Darlow abt 1827 Kirkby La Thorpe, Lincoln, Head, upholsterer
Mary A. Darlow abt 1827 Newark, Nottinghamshire, Wife
Sarah A. Spring abt 1861 Hull, Yorkshire, Niece
Annie Maria Farnham abt 1866 Barkston, Lincoln, Servant
1871
13 Gibralter Place, St George, London
Charles H Spring abt 1832 Nottinghamshire, Head, print compositor (unemployed)
Susannah Spring abt 1826 Lincolnshire, Wife
Alfred A Spring abt 1858 Hull, Yorkshire, Son
Sarah A Spring abt 1861 Hull, Yorkshire, Daughter
1861
Bruheim (??) Sq., Sculcoates St Paul, Yorkshire
Susanna Spring abt 1831 Spalding, Lincolnshire, Wife, printer compositor’s wife
Alfred Archer Spring abt 1858 Hull, Yorkshire, Son
Sarah Ann Spring abt 1860 Hull, Yorkshire, Daughter
(Couldn’t see Charles)
MARRIAGE
1854, June q., Spalding, Lincs
Archer, Susannah
Spring, Charles Huckbody
The latter is such a distinctive name that I looked it up specifically on Ancestry and came up with a great big family tree going back many generations! If you don't have access, you can tap into it through worldconnect at Roots.com.
It includes the following;
1 Charles Huckbody Spring b: ABT 1788 d: AFT 1851
+ Mary Conyers b: 1803 d: BEF 1851
2 Charles Spring b: 1831
2 Mary Jane Spring b: 1833
2 William Spring b: 1835
2 Rebecca Spring b: ABT 1848
If the Spring connection is correct, we could be on to something. (Have to find where the aunt or uncle fits.)
You may have to go to scotlandspeople to find more about James Sword

Turnbull (no wonder he was so insistent on his 'S').
Good fun!
Cheers,
Ros
