By 1914 its likely John would be at war and Ash street accomodation in 1913 could be a relative or boarding house or army barracks if John is not living there on 1911c
Hi Dobby,
if you read the thread again, you will see what Castana already has. Much of what you have said in the last two posts is either known already or not being requested.
1913- he is married from Ash Street
1914- he enlists from Oldham Road and his war record is known
1925- Mary Jane dies - certificate and grave is known
1927 - possible/probable death for John - grave now found if right person
Pre 1913- no sign of John in registers or censuses with the birth details he gives on enlistment - 1885 Newbiggin
As Ash street is earliest known address (marriage) that would be the first place to look.
Unfortunately, Electoral Rolls (the title of this thread) are not avaiable for 1911 and 1912.
An address search could be done by Castana for 1911 census but looks unlikely as there is no John Seymour around in free index for Failsworth.
Castana has not asked for newspaper trawling and parish searches in this post and other means you have referred to.
Often we can be successful on RC - in this case, the success will be the death and grave of JS if it is him which will provide the reason for the children being taken into care perhaps. So we have not failed but not been as successful as we had hoped - yet

regards
heywood
