A freind has helped me with this a bit. His age of 57, is probably 51 which ties in with Heathers info above,
Marriages Jun 1877
Christian Sarah Ann Nottingham 7b 448
FISHER Thomas Nottingham 7b 448
SHELLEY John Nottingham 7b 448
(from free BMD I think)
and John born 1850 (give or take 6 months) married Annie who was born in Nottm around 1853/4.
their kids:-
William born 1878 in Nottm
George born 1879/80 Nottm
Sarah A(probably Annie) born 1880/1 Derby
Rose born 1888 Derby
Nelly born 1890 Sheffield
Joseph born 1892 Sheffield
It would appear that Sarah Ann IS Annie - well done Heather

. I am getting less confused as time goes on.
I would still like to find more about John's background, but I (we) are/am getting there!
