I think his age when war broke out refers to WW1??
If these census are correct Joseph's daughter Sarah Jane was born abt 1882.
Sarah Jane Morris & Leonard Welsby married June Qtr 1911 Bolton, though on separate census they would have to be in the same area.

As to Joseph's death keep in mind he liked to change his age!!!
and checking deaths only in Farnworth which start at 1935.
Morris Joseph 82 Farnworth 8c 390 Deaths Jun 1937
Morris Joseph 76 Farnworth 8c 373 Deaths Dec 1942
MORRIS Joseph 76 Farnworth 10c 181 Deaths Dec 1952
Morris Joseph 68 Farnworth 10c 265 Deaths Mar 1955
MORRIS Joseph 63 Farnworth 10c 177 Deaths Dec 1957
Checking Bolton between 1920-1935 here is one of a few to choose
Deaths Mar 1921
Morris Joseph 68 Bolton 8c 338 [which fits c1853]
Someone else might like to share a thought
Finding Joseph in 1911 is a challenge even searching 10 year +/-
Again with age discrepancy can't see him in military records
