Hi Heather, Thanks for your reply.
I think the family were based in the Bradford/Beswick areas.
In 1911 the address is 16 Park Place, Bradford, Manchester. (Prestwich reg.district)
In 1936, his son is living at 18 Copestick Street, Ancoats,
and in 1948, His widow (Isabella Johnson) dies at the same address, 18 Copestick street, Ancoats.
John Johnson was born approximately 1863, in Bradford, Manchester. (According to census). This is my next challenge - to find his birth!
His occupations are listed as mill stoker, miller fireman, Boiler Fireman & General Labourer on the various census returns & certificates I have.
I hope this extra info can be of help.
Many thanks,
Benn.
