Hi
This could be his family in 1901:

RG13 / Piece: 3148 / Folio: 63 / Page: 17
Head: William PAGE 30, Railway Labourer, b Banbury, OxfordS
Wife: Sarah PAGE 25, b Langley, DerbyS.
Dau: Winifred PAGE 2, b Langley Mill
BIRTH: Winifred Maud PAGE - Mar Qtr 1899, Basford
Suggest you look for them - and John Thomas - here:
http://www.GenesReunited.co.uk/search.page/index/census_1911(This search shows places of birth
as transcribed)
Then search here (using the advanced search options, transcribed place of birth and 'other people in house' options - perhaps using Winfred as the 'other person' since her name is fairly unique):
