Aah! I see Amy Elizabeth Minshull was from Monks Coppenhall Cheshire, have you found her in the 1939 register?
The John Jackson above was still single in 1911 so 1st marriage was sometime after this census was taken.
Some more info on this Jackson family
(just in case this turns out to be your ancestor):
On the marriage certificate of John & Emma Jackson (nee Lewis) in 1877 Emma was recorded aged 20, John was recorded aged 39 and a Labourer but in the 1881 census he is recorded as aged 51 (perhaps he lied about his age due to the fact that there was such a large difference in their ages), his father John Jackson was also recorded as a Labourer as was William Lewis. Both bride and groom were of the parish and both signed.
In the 1881 census John was recorded as a Grocer and born in
Broxton Cheshire c1830)
