Thank you all.
Heather, I have the info on John Pike's death date, I also got it from cwgc which tells me his parents, Joseph and Sarah, his wife, Harriet and address in 1921, also his age, 56, was a Lance Corporal in Leicestshire reg and is buried in Nottingham General Cemetery.
The Irish connection is very interesting, maybe that is why Harriet can't be found 1901!
Thanks for now, I shall have to have a re-think!
