Joan,
I did not think it was you, His birthday was probably 14 Feb 1881 which ties in with him being 2 months old at the time of the 1881 census.
Son Bernard (5-3-1981)and his wife Isabella (17-7-1998) are both on Tamesides Burial register but since they started to "update" it - it is a shambles - so John and Agnes may well be there but not showing.
